The pulse rates of 158 randomly selected adult males vary from a low of 37 bpm to a high of 109 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 a n 239 Round up to the nearest whole number as needed b Assume that o 10 1 bpm based on the value s 10 1 bpm from the sample of 158 male pulse rates n CKIN Round up to the nearest whole number as needed
