Homework: Section 7.2 Question 9, 1.2.65 E T 5.47 of 9 points Homework Part 2 of 3 O Points: 0 of 1 Save The pulse rates of 174 randomly selected adult males vary from a low of 42 bpm to a high of 110 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 4 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 = 120 (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 174 male pulse rates. n = (Round up to the nearest whole number as needed.) Buy
