Thanks to an initiative to recruit top students, an administrator at a college claims that this year's entering class must have a greater
mean IQ score than that of entering classes from previous years. The administrator tests a random sample of 21 of this year's entering
students and finds that their mean IQ score is 115, with a standard deviation of 11. The college records indicate that the mean IQ score
for entering students from previous years is 113.
Is there enough evidence to conclude, at the 0.10 level of significance, that the population mean IQ score, µ, of this year's class is greater
than that of previous years? To answer, assume that the IQ scores of this year's entering class are approximately normally distributed.
Perform a one-tailed test. Then complete the parts below.
Carry your intermediate computations to three or more decimal places. (If necessary, consult a list of formulas.)

(d) Find the p-value. (Round to three or more decimal places.)
(e) Can we conclude that the mean IQ score of this year's class is greater than
that of previous years?
Yes ONo

Answers that need formulas must have them within the answer cell. A manager is trying to educate employees on the effects of personal health and workplace performance. The manager has gathered data from a group of employees to evaluate the effects of sleep and sickness. The manager asked employees to record the total number of hours of sleep they had over 10 working days in two weeks and compared it to the number of sick days that each took over those 10 days. Sick Days Total hours of sleep 0 80 2 40 1 60 0 70 3 50 2 90 4 35 1 68 0 72 2 55 The manager wonders if a non-linear model is a better relationship between the variables. Develop the model and run a regression adding the non-linear variable for total hours of sleep.

The data show the test results from students in two classrooms, one integrated and one not. There are two sets of test scores, a pre-test and a post-test for both groups. First, calculate a measure of change in the test scores for students in both groups. Then, use the resulting measure of change to compare both groups on the measure of change from the pre-test to the post-test. When finished, write a short summary of what you found, including: Group 1 mean Group 2 mean Ho and H1 t-observed t-critical
