Listed in the accompanying data table are student evaluation ratings of courses and​ professors, where a rating of 5 is for​ "excellent." Assume that each sample is a simple random sample obtained from a population with a normal distribution. a. Use the 93 course evaluations to construct a 95​% confidence interval estimate of the standard deviation of the population from which the sample was obtained.

b. Repeat part​ (a) using the 93 professor evaluations.

c. Compare the results from part​ (a) and part​ (b).

the required function is .

step-by-step explanation:

from the given table it is noticed that the graph passing through (-3,7), (0,4), (3,1) and (8,-4).

it is a linear function because the value of y is decrease by one as the value of x increase by 1.

the slope of the function is

the slope of the function is -1 and the y-intercept is 4.

the slope intercept form is

where, m is slope and b is y-intercept.

therefore the required function is . the graph of this function is shown below.
