(b) Find the critical value(s) and identify the rejection region(s).(c) Calculate d and sd.(d) Find the standardized test statistic t.(e) Decide whether to reject or fail to reject the null hypothesis and interpret the decision in the context of the original claim. 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 theamounts 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 didtake 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 isnormally distributed.
