The pulse rates of 175 randomly selected adult males vary from a low of 41 bpm to a high of 101 bpm. Find the minimum sample size required to estimate the mean pulse rate of adult males. Assume that we want 95% confidence that the sample mean is within 2 bpm of the population mean. Complete parts (a) through (c) below. a. Find the sample size using the range rule of thumb to estimate . n = 216 (Round up to the nearest whole number as needed.) b. Assume that o = 12.4 bpm, based on the value s = 12.4 bpm from the sample of 175 male pulse rates. n= (Round up to the nearest whole number as needed.)
