The pulse rates of 141 randomly selected adult males vary from a low of 40 bpm to a high of 112 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 3 bpm of the population mean. Complete parts (a) through (c) below.
a. Find the sample size using the range rule of thumb to estimate σ.
n = 239
(Round up to the nearest whole number as needed.)
b. Assume that σ = 10.8 bpm, based on the values = 10.8 bpm from the sample of 141 male pulse rates.
n =
