Suppose that a researcher is interested in estimating the mean systolic blood pressure,?, of executives of major corporations. He plans to use the blood pressures of a random sample of executives of major corporations to estimate?. Assuming that the standard deviation of the population of systolic blood pressures of executives of major corporations is24mm Hg, what is the minimum sample size needed for the researcher to be90% confident that his estimate is within3mm Hg of??Carry your intermediate computations to at least three decimal places. Write your answer as awhole number(and make sure that it is the minimum whole number that satisfies the requirements).(If necessary, consult alist of formulas.)
