Step-by-step explanation:
A personnel manager has found that, historically, the scores on aptitude tests given to applicants for entry-level positions follow a normal distribution with standard deviation 21.73 points. A random sample of 14 test scores from the current group of applicants had a mean score of 74.57 points. Based on these sample results, a statistician found for the population mean a confidence interval extending from 65.7425 to 83.3975 points. Find the confidence level of this interval. Round off your answer to two decimal places.
Answers
Answer:
The value is [tex]C = 85\%[/tex]
Step-by-step explanation:
From the question we are told that
The standard deviation is [tex]\sigma = 21.73[/tex]
The sample size is n = 14
The mean score is [tex]\= x = 74.57[/tex]
The confidence interval is 65.7425 to 83.3975
Generally the degree of freedom is mathematically represented as
[tex]df = n -1[/tex]
=> [tex]df = 14 -1[/tex]
=> [tex]df = 13[/tex]
Generally the margin of error is mathematically evaluated as
[tex]E = \frac{83.3975 -65.7425 }{2}[/tex]
=> [tex]E = 8.828[/tex]
Generally this margin of error is mathematically represented as
[tex]E = t_{\frac{\alpha }{2} , df} * \frac{\sigma }{\sqrt{n} }[/tex]
=> [tex]8.828 = t_{\frac{\alpha }{2} , df} * \frac{21.73 }{\sqrt{14} }[/tex]
=> [tex]t_{\frac{\alpha }{2} , df} = 1.520[/tex]
From the t distribution table the probability of [tex]( t> 1.520 )[/tex] at a degree of freedom of 13 is
[tex]\frac{\alpha }{2} = P( t > 1.52 ) = 0.076[/tex]
=> [tex]\alpha = 2 * 0.076[/tex]
=> [tex]\alpha = 1.52[/tex]
So the confidence level is evaluated as
[tex]C = 1- \alpha[/tex]
=> [tex]C = 1- 0.152[/tex]
=> [tex]C = 0.85[/tex]
Converting to percentage
=> [tex]C = 0.85 * 100[/tex]
=> [tex]C = 85\%[/tex]

----% of 50 shirts is 35 shirts
Answers
Answer:
70%
Step-by-step explanation:
50/10 is 5 (which is 10%). 5 x 7 is 35 (or 70%)
For this type of problem we can use a ratio. Using a ratio allows us to to find how much needs to be multiplied by 50 to get 35 (or our percentage needed).
To write the ratio we can say “for every 50 shirts there are 35 once multiplied by a certain percentage”. The ratio would be written out as 35:50. We need to find a way to get 50 to 35 by multiplying (by the percentage). To find the percentage we need to divide 35 by 50. 35/50=0.7.
When working with percentages, decimals will be multiplied by 100 and transferred to a percentage (0.7*100=70 which is then 70%. Multiplying 50 by 0.7 (or 70%) will then give you 35.
The heights of women aged 20 to 29 are approximately Normal with mean 64.3 inches and standard deviation 2.7 inches. Men the same age have mean height 69.9 inches with a standard deviation 3.1 inches. Describe in lay terms what information the z scores give that the original nonstandardized heights do not.
Answers
Answer:
In a lay term; The z-score gives us information concerning how many percentages of data lie between the given data interval. The z-score gives us an overview of the distance from the mean a data point is. In addition to that, it measures the degree of standard deviations below or above the population mean a raw score. We can place a z-score on a normal distribution curve.
Step-by-step explanation:
Given that:
Height of woman between age 20 -29 are approximately normal with:
population mean = 64.3 inches &;
standard deviation = 2.7
For men:
population mean = 69.9 inches
Standard deviation = 3.1 inches
In a lay term; The z-score gives us information concerning how many percentages of data lie between the given data interval. The z-score gives us an overview of the distance from the mean a data point is. In addition to that, it measures the degree of standard deviations below or above the population mean a raw score.

The best estimate of the fraction 29/40 would be; 0.7
How can we interpret the division?When 'a' is divided by 'b', then the result we get from the division is the part of 'a' that each one of 'b' items will get. Division can be interpreted as equally dividing the number that is being divided into total x parts, where x is the number of parts the given number is divided.
We need to find the decimal that best best estimate of the fraction 29/40
A negative divided by a negative is positive, then;
29/40 = 0.72
Therefore, The best estimate of the fraction 29/40 would be; 0.7

Point A is rotated 90 degrees counterclockwise around point C to form the image A'. Select three true statements based on the given information.
Answers
Answer:
When we rotate a point A, around point C, the distance between the points is invariant.
This means that if A' es the image of the rotated point, then A' must lie in a circle centered in C with radius AC.
Then the correct statements are:
A' lies on a circle centered at point C with radius AC
This is by definition.
m∠ACA' = 90°
This is because A is rotated 90° around C to form the image A', then the measure must be 90°.
AC = A'C
As we already defined, the distance between the rotated point and the center of rotation is invariant, then the distance between A and C must be the same as the distance between A' and C.
Answer:
AC = A'C
A' lies on a circle centered at point C with radius AC
m∠ACA' = 90°
Step-by-step explanation:
When we rotate a point A, around point C, the distance between the points is invariant.
This means that if A' es the image of the rotated point, then A' must lie in a circle centered in C with radius AC.
As we already defined, the distance between the rotated point and the center of rotation is invariant, then the distance between A and C must be the same as the distance between A' and C.
