Carry answer 3 decimal places and round up to nearest whole number

AA 8 www-awn.aleks.com C, O CONFIDENCE INTERVALS AND HYPOTHESIS TESTING . . . . Nicholas V Choosing an appropriate sample size V Suppose that a researcher is interested in estimating the mean systolic blood pressure, p, of executives of major corporations. He plans to use the blood pressures of a random sample of executives of major corporations to estimate 14. Assuming that the standard deviation of the population of systolic blood pressures of executives of major corporations is 25 mm Hg, what is the minimum sample size needed for the researcher to be 90% confident that his estimate is within 3 mm Hg of 11? Carry your intermediate computations to at least three decimal places. Write your answer as a whole number (and make sure that it is the '3 minimum whole number that satisfies the requirements).
