Extracted text: The pulse rates of 178 randomly selected adult males vary from a low of 38 bpm to a high of 114 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 o. n = (Round up to the nearest whole number as needed.)
