The pulse rates of 171 randomly selected adult males vary from a low of 42 bpm to a high of 106 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 o. n= 107 (Round up to the nearest whole number as needed.) b. Assume that a = 11.7 bpm, based on the value s = 11.7 bpm from the sample of 171 male pulse rates. n=0 (Round up to the nearest whole number as needed.)
