The systolic blood pressure (given in millimeters) of males has an approximately normal distribution with mean u = 125 andstandard deviation o = 12.(a) Calculate the z-scores for the male systolic blood pressures 110 and 140 millimeters. (Round your answers to twodecimal places.)110 mmz =140 mmz =(b) If a male friend of yours said he thought his systolic blood pressure was 2.5 standard deviations below the mean, butthat he believed his blood pressure was between 110 and 140 millimeters, what would you say to him? (Enter yournumerical answer to the nearest whole number.)He is ---Select--- because 2.5 standard deviations below the mean would give him a blood pressure reading ofmillimeters, which is ---Select--- the range of 110 to 140 millimeters.

Solve the problem. The systolic blood pressures of the patients at a hospital are normally distributed with a mean of 138 mmHg and a standard deviation of 12.8 mmHg. Find the two blood pressures having these properties: the mean is midway between them and 90 % of all blood pressures are between them. (Hint: the area between the two values is 0.9. Since they are symmetrical on either side of the mean, that leaves an area of 0.1 divided by 2 = 0.05 in the tails of the distribution.) ο οο 126.5 mm Hg, 149.5 mm Hg 116.9 mm Hg, 159.1 mm Hg 117.9 mm Hg, 160.1 mm Hg O.121.6 mm Hg, 154.4 mm Hg
