A researcher claims that a post-lunch nap decreases the amount of time it takes males to sprint 20 meters after a night with only 4 hours of sleep. The table shows the amounts of time (in seconds) it took for 10 males to sprint 20 meters after a night with only 4 hours of sleep when they did not take a post-lunch nap and when they did take a post-lunch nap. At a = 0.10, is there enough evidence to support the researcher's claim? Assume the samples are random and dependent, and the population is normally distributed. Complete parts (a) through (e) below.

Many university admission committees use the GMAT score as one of the critical indicators of how well a student is likely to perform in an MBA program. However, the GMAT might not be a very strong indicator for all MBA programs. Suppose that an MBA program designed for middle managers who wish to upgrade their skills was launched 3 years ago. To judge how well the GMAT scores predict MBA performance, a sample of 12 graduates was taken. Their GPA in the MBA program (values 0 to 12) and their GMAT scores (values ranging from 200 to 800) are listed below. Compare the covariance and the correlation coefficient. Interpret your findings. GMAT GPA 599 9.6 689 8.8 584 7.4 631 10.0 594 7.8 643 9.2 656 9.6 594 8.4 710 11.2 611 7.6 593 8.8 683 8.0
