The pulse rates of 153 randomly selected adult males vary from a low of 43 bpm to a high of 107 bpm. Find the minimum sample size required to estimate the mean pulse rate of adult males. Assume that we want 99​% confidence that the sample mean is within 4 bpm of the population mean. Complete parts​ (a) through​ (c) below. a. Find the sample size using the range rule of thumb to estimate sigma. b. Assume that σ=11.4 ​bpm, based on the value s=11.4 bpm from the sample of 153 male pulse rates.   c. Compare the results from parts​ (a) and​ (b). Which result is likely to be​ better

The pulse rates of 153 randomly selected adult males vary from a low of 43 bpm to a high of 107 bpm. Find the minimum sample size required to estimate the mean pulse rate of adult males. Assume that we want 99​% confidence that the sample mean is within 4 bpm of the population mean. Complete parts​ (a) through​ (c) below.

a. Find the sample size using the range rule of thumb to estimate sigma.

b. Assume that σ=11.4 ​bpm, based on the value
s=11.4 bpm from the sample of
153 male pulse rates.
 
c. Compare the results from parts​ (a) and​ (b). Which result is likely to be​ better
