The pulse rates of 144 randomly selected adult males vary from a low of 36 bpm to a high of 116 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 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. n= (Round up to the nearest whole number as needed.) b. Assume that o=11.8 bpm, based on the value s = 11.8 bpm from the sample of 144 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 (b). The result from The result from part (a) is because is likely to be better
