Essay

Solve the problem.
-The mean resting pulse rate for men is 72 beats per minute. A simple random sample of men who regularly
work out at Mitch's Gym is obtained and their resting pulse rates (in beats per minute) are listed below. Use a
0.05 significance level to test the claim that these sample pulse rates come from a population with a mean less
than 72 beats per minute. Assume that the standard deviation of the resting pulse rates of all men who work out
at Mitch's Gym is known to be 6.6 beats per minute. Use the traditional method of testing hypotheses. $$\begin{array} { l l l l l l l } 54 & 59 & 69 & 84 & 74 & 64 & 69 \\70 & 66 & 80 & 59 & 71 & 76 & 63\end{array}$$
