The pulse rates of 143 randomly selected adult males vary from a low of 43 bpm to a high of 103 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.
