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 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 = 0.05. is there enough evidence to support the researchers claim? Assume the samples are random and dependent, ant population is normally distributed. Complete parts (a) through (6) below. Sprint time (without nap) Sprint time (with nap) 10% m (a) Identify the claim and state H0 and Ha- What is the claim? 0 A. A night with only 4 hours of sleep increases the amount of time it takes males to sprint 20 meters. 0 B. A postlunch nap decreases the amount of time it takes males to sprint 20 meters. 0 C. A night with only 4 hours of sleep decreases the amount of time it takes males to sprint 20 meters. 0 D. A postlunch nap increases the amount of time it takes males to sprint 20 meters
