The pulse rates of

155

randomly selected adult males vary from a low of

44

bpm to a high of

108

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

2

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

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

σ.

n=425425

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

1. Assume that

σ=10.1

​bpm, based on the value

s=10.1

bpm from the sample of

155

male pulse rates.
