3. The wildlife department has been feeding a special food to rainbow trout finger lings in a pond. A sample of the weight of 40 trout revealed that the mean weight is 402.7 grams and the standard deviation 8.8 grams. ( 4 POINTS) 1. What is the point estimated mean weight of the population? What is that estimate called? 2. What is the 99 percent confidence interval? 3. What are the 99 percent confidence limits? 4. Interpret your findings?
Answer:
1) 402.7 grams. This estimate is called the sample mean.
2) (399.11, 406.29)
3) The 99 percent confidence limits is between 399.11 grams and 406.29 grams.
I am 99% sure that the value lies between 399.11 grams and 406.29 grams.
Explanation:
sample size (n) = 40, the mean weight (x)= 402.7 grams and the standard deviation (σ)=8.8 grams
1) The point estimated mean weight of the population is 402.7 grams. This estimate is called the sample mean.
2) c = 99% = 0.99
α = 1 - 0.99 = 0.01
[tex]\frac{\alpha }{2} =\frac{0.01}{2} =0.005[/tex].
The z score of 0.005 corresponds with the z score of 0.495 (0.5 - 0.005).
[tex]z_\frac{\alpha }{2} =2.58[/tex].
The margin of error (e) = [tex]z_\frac{\alpha }{2}*\frac{\sigma}{\sqrt{n} } =2.58*\frac{8.8}{\sqrt{40} } =3.59[/tex]
The confidence interval = x ± e = 402.7 ± 3.59 = (399.11, 406.29)
3) The 99 percent confidence limits is between 399.11 grams and 406.29 grams.
I am 99% sure that the value lies between 399.11 grams and 406.29 grams.
Assignment 8: Calendar Create a calendar program that allows the user to enter a day, month and year in three separate variables. Then ask the user to select froma menu of choices using this formatting: Please enter a date Day: Month: Year: Menu: 1) Calculate the number of days in the given month. 2) Calculate the number of days left in the given year t must include the following functions: ter and returns a 1 if a year is a leap year et and O if it is not. This information will only be used by other functions umber of days: This subprogram will accept the date as parameters and return how many days are in the given monthe. the date as parameters and then calculate the number of days left in the year. This should not include the date the user entered in the count
this is what I have so far:
def number_of_days(m):
if (m == 1,3,5,7,8,9,11):
woh = 31
elif (m == 2):
woh = 28
elif (m == 4,6,10,12):
woh = 30
print (woh)
print (29)
def days_left(d,m,y):
if (d > 0):
print ('135')
def leap_year(d,m,y):
if (d > 0):
print ('1')
day = int(input('Enter the day.'))
month = int(input('Enter the month.'))
year = int(input('Enter the year.'))
menu = int(input('Day in month or left in year? (1,2)'))
if (menu == 1):
monthdays = number_of_days(month)
print (monthdays)
elif (menu == 2):
dayleft = days_left(day,month,year)
print (dayleft)
Answer:
Following are the correct code to this question:
def leap_year(year):#defining a method to check if year is leap year
if ((year%4==0) and (year%100!=0)) or (year%400==0):#defining condition to check value
return 1 #return value 1
return 0 #return 0
def number_of_days(month,year):#defining method number_of_days to calculate year or month is leap year are not
if month==2: #defining if block to calculate leap year value
if leap_year(year):#using if block to call leap_year month
return 29#return value 29
return 28 #return value 28
if month in days_31: #defining if block to calculate day
return 31 #return value 31
return 30#return value 30
def days_left(day,month,year):#defining method days_Left
daysLeft = number_of_days(month,year)-day#defining variable daysLeft which calls number_of_days method
month += 1 #increment month variable value by 1
while month<=12:#defining while loop to Calculate left days
daysLeft += number_of_days(month,year) #using daysLeft variable to hold number_of_days value
month += 1 #increment value of month variable by 1
return daysLeft #return daysLeft value
days_31 = [1,3,5,7,8,10,12] #defining days_31 dictionary and assign value
days_30 = [4,6,9,11] # defining days_30 dictionary and assign value
print('Please enter a date') #print message
day = int(input('Day: ')) #defining day variable and input value
month = int(input('Month: '))#defining Month variable and input value
year = int(input('Year: '))#defining Year variable and input value
print('Menu:')#print message
print('press 1 to Calculate the number of days in the given month.')#print message
print('press 2 to Calculate the number of days left in the given year.')#print message
choice = int(input())#defining choice variable and input the value
if choice==1: #defining if block to check choice
print(number_of_days(month,year)) #call method number_of_days and print value
elif choice==2: #defining elif block to check value
print(days_left(day,month,year))#call days_left and print value
Output:
Please enter a date

Explanation:
In the given python code, three methods "leap_year, number_of_days, and days_left " is declared, in which we calculate all the values that can be described as follows:
In the leap_year method, it accepts the year variable, which calculates the year is the leap year and returns its value that is 1. In the next method number_of_days, it is declared that accepts the "year and month" variable as the parameter and calculates and returns its value. In the last days_left method, it calculates the left days and returns its value, and outside the method, two dictionary variable days_31 and days_30 is declared, which assign a value and used use three input variable day, month, and year variable to accepts user input value. In the next step, a choice variable is declared, that input values and calls and print its value accordingly.The calendar program illustrates the use of conditional statements
In programming, conditional statements are used to make decisions.
The calendar program in Python where comments are used to explain each line is as follows:
#This defines the function that calculates the days in a month
def daysMonth(month,year):
#This checks for leap year (i.e. February), and returns the number of days
if month==2:
if ((year%4==0) and (year%100!=0)) or (year%400==0):
return 29
return 28
#This checks and returns the number of days in the other months
if month in [1,3,5,7,8,10,12]:
return 31
return 30
#This defines the function that calculates the days remaining in a year
def countDays(day,month,year):
#This calculates the days remaining in the current month
daysLeft = daysMonth(month,year)-day
month += 1
#The following loop determines the days left in the year
while month<=12:
daysLeft += daysMonth(month,year)
month += 1
#The returns the days left in the year
return daysLeft
#This gets the day as input
day = int(input('Day: '))
#This gets the month as input
month = int(input('Month: '))
#This gets the year as input
year = int(input('Year: '))
#This gets the choice
choice = int(input("1 - Days in the month\n2 - Days left in the year\nChoice: "))
#If the choice is 1, this prints the days in the month
if choice==1:
print("There are",daysMonth(month,year),"days in the month")
#If the choice is 2, this prints the days left in the year
elif choice==2:
print("There are",countDays(day,month,year),"left in the year")

3. Bob is arguing that if you use output feedback (OFB) mode twice in a row to encrypt a long message, M, using the same key each time, it will be more secure. Explain why Bob is wrong, no matter what encryption algorithm he is using for block encryption (15 points).
Answer:
Bob was wrong in his argument because from the cipher text C₂ only the initialization vector is encrypted two times and XOR with plain text M.
Also it will not provide a better security than the first because it's encryption was done only on initialization vector and not the plain text.
Explanation:
Solution
From the given question, in the output feedback mode (OFB) the following Encryption Algorithm is stated as follows:
Where,
V₀ = vector initialization
V₁ = Ek (Vi-₁)
Ek = The encryption algorithm
C₁ =V₁⊕ M₁
Here,
C₁ = this is the cipher text
M₁ = Plain text for it^th session
Thus
The Decryption Algorithm is shown below:
M₁=V₁⊕ C₁
In this case, when bob encrypt the message M for the first time in the OFB method, the cipher text is
C₁ =V₁⊕ M₁
So,
C₁ =Ek (V₀) ⊕ M
Hence the Cipher text C₁ the initialization vector only is encrypted
Thus,
When Bob does a second encryption, the Cipher text will be
C₂ =Ek (V₁) ⊕ C₁
C₂ = Ek (Ek (V₀)) ⊕ Ek (V₀) ⊕ M
Finally, from the cipher text C₂ only the initialization vector encrypted twice and XOR with plain text M. so it will not provide a better security than the first because it's encryption was carried out on initialization vector without the plain text.

Observa el siguiente dibujo, y sabiendo que el engranaje motriz tiene 14 dientes y gira a 4000 RPM, y el conducido tiene 56 dientes, responde: a) Se trata de una transmisión que aumenta o reduce la velocidad? b) Calcula en número de revoluciones por minuto de la rueda conducida.
Answer:
A) reduce the velocity
B) 1000 rpm
Explanation:
A) Given that the driven gear wheel has more teeth (56) than the driver gear wheel (14), then the velocity is reduced.
B) Given that:
number of teeth * revolutions per minute = constant
then:
14*4000 = 56000
56*rpm = 56000
rpm = 56000/56
rpm = 1000

One way he can achieve his aim is by including comments to his code.
He can include as many comments as he likes because comments are non executable part of the program. In other words, the translators omit comments during program translation.
Another reason why he should consider using comments is that comments are used by computer programmers to explain lines of code especially the difficult lines.
In fact programmers are advised to include comments in their programs because comments doesn't have to be structured and can be expressed in human language.

Explanation:
In which part of a presentation should you provide background information, ask a thoughtful question, or offer an interesting
fact?
opening
outline
body
closing
The correct answer is A. Opening
Explanation:
In a presentation or the text, the opening is the first section that should allow the audience to understand what is the topic and focus. This is achieved through a hook that can include an interesting fact or a rhetorical question (a question that makes the audience think) because these two elements grab the attention of the audience. Additionally, after the hook, it is common to provide background information about the topic of the presentation, and finally, the speaker will state the main point or thesis statement. This occurs before the body of the presentation, which is the main section, and the closing, which is the last section. Thus, elements such as background information or an interesting fact are part of the opening.

Ptolemy believed that Earth was at the center of the universe. Kepler believed that the sun was at the focus of Earth's elliptical orbit. Which of these statements best explains why Ptolemy and Kepler made different observations about the solar system?
The focus of their study was different.
or
They could not match the data with the observations.
Answer:
The correct option is;
They could not match the data with the observations
Explanation:
Ptolemy proposed the geocentric model based on the observation that the from there are equal number of above and below the horizons at any given time, which didn't match the data observed
Kepler believed the Sun was the focus of Earth's elliptical orbit due to disparities between data in Tycho Brahe's astronomical records and the geocentric model of the solar system.
Therefore, Ptolemy and Kepler made different observations about the solar system because they could not match the data with the observations.
Answer:
the second one.
