The pulse rates of 140 randomly selected adult males vary from a low of 45 bpm to a high of 121 bpm.Find the minimum sample size required to estimate the mean pulse rate of adult males. Assume that wewant 99% confidence that the sample mean is within 2 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 = 599(Round up to the nearest whole number as needed.)b. Assume that o = 10.2 bpm, based on the value s = 10.2 bpm from the sample of 140 male pulse rates.n=(Round up to the nearest whole number as needed.)

Answer Given confidence interval =99%Margin of error [E] =2Max value =121Min value =45
