The pulse rates of 163 randomly selected adult males vary from a low of 39 bpm to a high of 107 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 o (Round up to the nearest whole number as needed.) b. Assume that G = 10.6 bpm, based on the value s = 10.6 bpm from the sample of 163 male pulse rates. n (Round up to the nearest whole number as needed.) c. Compare the results from parts (a) and (b). Which result is likely to be better? The result from part (a) is the result from part (b). The result from is likely to be better because
