Question
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 0.01, 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. Male Sprint time (without nap) 1 2 3 4 5 6 8 9 10 4.01 3.93 3.95 4.05 3.96 4.06 3.93 4.05 3.97 3.95 Sprint time (with nap) 4.00 3.93 3.94 4.05 3.93 4.04 3.94 4.02 3.98 3.92 OD.
