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 1 2 3 4 5 6 7 8 9 10 Sprint time (without nap) 3.91 3.92 3.96 3.91 3.93 3.95 3.97 3.92 3.95 3.91 . . ... (a) Identify the claim and state Ho and Ha What is the claim? O A. A night with only 4 hours of sleep increases the amount of time it takes males to sprint 20 meters. O B. A night with only 4 hours of sleep decreases the amount of time it takes males to sprint 20 meters
