The pulse rates of 175 randomlyr selected adult males vary from a low of 45 bpm to a high of 'l 13 bpm. Find the minimum sample size required to estimate the mean pulse rate of adult males. Assume that we want 95% condence that the sample mean is within 4 bpm of the population mean. Complete parts {a} through to) below. a. Find the sample size using the range rule of thumb to estimate 6. n=3 [Round up to The nearest whole number as needed.) Use the given information to find the number of degrees of freedom, the critical values x_ and yo , and the confidence interval estimate of o. It is reasonable to assume that a simple random sample has been selected from a population with a normal distribution.
