Step-by-step explanation:
Problem Andrey works at a call center, selling insurance over the phone. While debating which greeting he should use when calling potential customers — "Howdy!" or "Hiya!" — he decided to conduct a small study. For his subsequent 500500500 calls, he chose one of the greetings randomly by flipping a coin, and used the same script for his sale otherwise. Then, he compared the percentage of calls he succeeded in selling insurance using each greeting. He noticed that he was significantly more likely to make a sale in calls that started with "Hiya!" Can we conclude that the greeting caused the difference in sales? Why? Choose 1 answer:
Answer:
Yes, because the calls were each randomly assigned a greeting.
Step-by-step explanation:
It is given that Andrew who works at the call center of an insurance company, decided to conduct a small survey on how to greet the potential customers while calling.
For this, he uses his 500 subsequent calls and he chooses to greet his customers randomly as "Howdy" or "Hiya".
Since the selection bias is ruled out, the calls were randomly assigned for the greetings. Thus the greetings caused a difference in sales.
Answer:
Yes, because the calls were each randomly assigned a greeting
Step-by-step explanation:
Random assignment to treatment groups makes this study an experiment, so we can make causal conclusions.

What is mid point theorem?The mid point theorem states that in a triangle the line segment joining the mid point of two sides is always parallel and equal to half of the length of the third side.
As per the given figure the data is as follows,
The line segment of length 6x + 7 is parallel to the side of a triangle of length 19x - 28 such that it divides other two sides equally.
Apply mid point theorem to obtain,
6x + 7 = 1/2(19x - 28)
=> 19x/2 - 6x = 14 - 7
=> 7x/2 = 7
=> x = 2
Hence, the value of x for the given triangle is 2.

A newsgroup is interested in constructing a 90% confidence interval for the proportion of all Americans who are in favor of a new Green initiative. Of the 533 randomly selected Americans surveyed, 351 were in favor of the initiative. Round answers to 4 decimal places where possible.
Answer:
The 90% confidence interval for the proportion of all Americans who are in favor of a new Green initiative is (0.6247, 0.6923).
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.
[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
In which
z is the z-score that has a p-value of [tex]1 - \frac{\alpha}{2}[/tex].
Of the 533 randomly selected Americans surveyed, 351 were in favor of the initiative.
This means that [tex]n = 533, \pi = \frac{351}{533} = 0.6585[/tex]
90% confidence level
So [tex]\alpha = 0.1[/tex], z is the value of Z that has a p-value of [tex]1 - \frac{0.1}{2} = 0.95[/tex], so [tex]Z = 1.645[/tex].
The lower limit of this interval is:
[tex]\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.6585 - 1.645\sqrt{\frac{0.6585*0.3415}{533}} = 0.6247[/tex]
The upper limit of this interval is:
[tex]\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.6585 + 1.645\sqrt{\frac{0.6585*0.3415}{533}} = 0.6923[/tex]
The 90% confidence interval for the proportion of all Americans who are in favor of a new Green initiative is (0.6247, 0.6923).
which triangle is similar to triangle t?
Answer:
It's the one with 30 and 110
Step-by-step explanation:
Every triangle is 180. So The one shown has 40 and 110. Which is 150. So you're missing 30.
On the last option it's 30 and 110 which is 140. You're missing the 40.

Jovi distributed 3(n+2) and got 3 x n + 3 x 6 is his answer correct
Answer:
Step-by-step explanation:
since 3 is outside the parenthesis (n + 2) you multiply the 3 by the n and the 2 and
3n + 6
next subtract the 6 and add the 6 to the other side
3n - 6 = 6
3n = 6

The standard form equation is
(x - h)² + (y - k)² = r²
(h, k) is the center
r is the radius

Answer:
[tex]d=27.20[/tex] units or [tex]2\sqrt{185}[/tex] units
Step-by-step explanation:
(14, -1) and (-8, - 17)
To find the distance of two points, we use the distance formula:
[tex]d = \sqrt{(x_{2}-x_1)^2 + (y_2-y_1)^2 }[/tex]
Let's plug in what we know.
[tex]d = \sqrt{(-8-14))^2 + (-17-(-1))^2 }[/tex]
Evaluate the double negative.
[tex]d = \sqrt{(-8-14))^2 + (-17+1)^2 }[/tex]
Evaluate the parentheses.
[tex]d = \sqrt{(-22)^2 + (-16)^2 }[/tex]
Evaluate the exponents.
[tex]d = \sqrt{(484) + (256) }[/tex]
Add.
[tex]d=\sqrt{740}[/tex]
Evaluate the square root.
[tex]d=27.20[/tex] units or [tex]2\sqrt{185}[/tex] units

Answer:
AB = 5.6 cm
Step-by-step explanation:
From the question given above, the following data were obtained:
Angle θ = 62°
Hypothenus = BC = 12 cm
Adjacent = AB =?
The lenght of side AB can be obtained by using Cos θ ratio. This is illustrated:
Cos θ = Adjacent / Hypothenus
Cos 62 = AB / 12
0.4695 = AB / 12
Cross multiply
AB = 0.4695 × 12
AB = 5.6 cm
Thus, length AB is 5.6 cm

Step-by-step explanation:
If you shorten 0.725, it is 0.72 vs 0.75, making 0.75 the larger number.

Nope

Think of it like this:
forget the 5 in the THOUSANDTHS place because thats basically, well you can think of it as the ones place now lets look at both of their HUNDREDTHS place.

For the following scenarios, determine whether or not they represent paired samples.
a. Test scores for students in a biology class taught by Professor Quick are being compared to test scores in a different section of the biology class taught by Professor Quack
b. Pulse rates for students at the beginning of class are being compared to pulse rates for the same students at the end of class.
c. The weights of 10-year-olds in 2009 are being compared to the weights of 10- year-olds in 1994.
Answer:
A = Not a paired sample
B = paired sample
C = Not a paired sample
Step-by-step explanation:
Paired samples also commonly referred to as dependent samples are often characterized by having to different data points which are taken at different times, location and so on. Such that each pair of data points or observation can be matched based on the basis of the subject or sample name usually for the sake of analysing if any statistical difference exists between the occurrence of each observation.
For the instances given above ;
a.) this isn't a paired sample, because Professor Quick and Professor Quacks students are different, hence each student has only one reading and as such a match of the two test scores cannot be made on the basis of student name or identity. Hence, it is not a paired sample
B.) This is a paired sample, two different readings are available for each students ; one at the beginning, the other at the end. Hence, it is a paired sample
C.) This is not a paired sample, because the subjects used to obtain the weight of 10 year old in 1994 aren't the same samples used in 2009
in a certain lake 30% of the fish are thrown back because they are too small. Consider catching 20 fish from the lake. Assume that the fish you caught can be considered a random sample from the very large number of fish in the lake. does this represent a binomial setting
Answer:
Binomial probability distribution concept & application, example
Step-by-step explanation:
Yes, this represents a binomial setting. As, it is used for finding probability of - particular number of success outcomes , from repetitive or multiple events.
Here
Success {Event P} ie small fish, with prob = 30% = 0.3 .Failure {Event Q} ie large fish, with prob = 70% = 0.7Number of trials = 20. Let r be number of small fishes out of 20 fishes.Binomial probability = N c r . (P)^r . (Q)^ (n-r)
Ex : P( 5 small fish out of 20) = 20c5 (0.30)^5 (0.70)^15

3. (G.11C) A right cylinder has a total surface area of 1301 cm?. If the diameter of
the cylinder is 10 cm, what is the height?
X
A 8 cm
B 10 cm
C 9 cm
D 12 cm
Answer:
A. 8 cm
Step-by-step explanation:
Total surface of a cylinder = 130π cm²
Diameter (d) = 10 cm
Radius (r) = 10/2 = 5 cm
Height = ?
Formula for total surface area of cylinder = 2πrh + 2πr²
Plug in the values
130π = 2*π*5*h + 2*π*5²
130π = 10hπ + 50π
130π = π(10h + 50)
Divide both sides by π
130 = 10h + 50
Subtract 50 from each side
130 - 50 = 10h
80 = 10h
Divide both sides by 10
80/10 = 10h/10
8 = h
h = 8 cm
