The average resting heart rate for all college students in theU.S. is 70 beats per minute (bpm). The resting heart rate isgenerally lower in physically fit people and higher in those whoare not fit. Researchers at the Student Health Service at TexasA&M University want to test their theory that the averageresting heart rate of A&M students is not the same as theresting heart rate of all college students in general. Unknown tothe researchers, suppose that IN REALITY the average resting heartrate for all A&M students is 68 bpm.

What null and alternative hypotheses should the researchersuse?

a) The null hypothesis should be "The mean resting heart ratefor all A&M students is less than 70 bpm" and the alternativehypothesis should be "The mean resting heart rate for all A&Mstudents is equal to 70 bpm".

b) The null hypothesis should be "The mean resting heart ratefor all A&M students in the sample is equal 70 bpm" and thealternative hypothesis should be "The mean resting heart rate forall A&M students in the sample is not equal to 70bpm".

c) The null hypothesis should be "The mean resting heart ratefor all A&M students is equal 70 bpm" and the alternativehypothesis should be "The mean resting heart rate for all A&Mstudents is not equal to 70 bpm".

d) The null hypothesis should be "The mean resting heart ratefor all A&M students is equal 68 bpm" and the alternativehypothesis should be "The mean resting heart rate for all A&Mstudents is not equal to 68 bpm".

e) The null hypothesis should be "The mean resting heart ratefor all A&M students is more than 68 bpm" and the alternativehypothesis should be "The mean resting heart rate for all A&Mstudents is equal to 68 bpm".
