Resting pulse rate is an important measure of the fitness of a persons cardiovascular system, with a lower rate indicative of greater fitness. The mean pulse rate for all adult males is approximately 72 beats per minute. A random sample of 25 male students currently enrolled in the Agriculture School at a major university was selected and the mean resting pulse rate was found to be 80 beats per minute with a standard deviation of 20 beats per minute. The experimenter wishes to test if the students are less fit, on average, than the general population. The null and alternative hypotheses are:

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

Resting pulse rate is an important measure of the fitness of a person’s cardiovascular system, with a lower rate indicative of greater fitness. The mean pulse rate for all adult males is approximately 72 beats per minute. A random sample of 25 male students currently enrolled in the Agriculture School at a major university was selected and the mean resting pulse rate was found to be 80 beats per minute with a standard deviation of 20 beats per minute. The experimenter wishes to test if the students are less fit, on average, than the general population. The null and alternative hypotheses are:

A	H0:
B	H0:x-bar = 72; Ha:x-bar < 72
C	H0:
D	H0:x-bar = 80; Ha:x-bar > 72
E	H0:

Explanation:

Detailed explanation-1: -Resting heart rate can predict cardiovascular morbidity and mortality. Measurements are easy to obtain, and monitoring heart rate can help in cardiovascular disease prevention and management.
