5. The pulse rates of 179 randomly selected adult males vary from a low of 44 bpm to a high of 108 bpm. Find the minimum sample size required to estimate the mean pulse rate of adult males. Assume that we want 90% 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=10.6 bpm, based on the value s=10.6 bpm from the sample of 179 male pulse rates. n=? c.
