The pulse rates of 176 randomly selected adult males vary from a low of 35 bpm to a high of 111 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 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 σ. n=___   B.  Assume that σ=10.1 ​bpm, based on the value s=10.1 bpm from the sample of 176 male pulse rates.   C. Compare the results from parts​ (a) and​ (b). Which result is likely to be​ better?
