The pulse rates of 162 randomly

selected adult males vary from a low of

bpm to a high of

bpm. Find the minimum sample size required to estimate the mean pulse rate of adult males. Assume that we want

confidence that the sample mean is within

bpm of the population mean. Complete parts​ (a) through​ (c) below.

Assume that

​bpm, based on the value

bpm from the sample of

male pulse rates.

​(Round up to the nearest whole number as​ needed.)
