The systolic blood pressure (given in millimeters) of males has an approximately normal distribution with mean u = 135 and standard deviation o = 18. (a) Calculate the z-scores for the male systolic blood pressures 110 and 160 millimeters. (Round your answers to two decimal places.) 110 mm Z = 160 mm z = (b) If a male friend of yours said he thought his systolic blood pressure was 2.5 standard deviations below the mean, but that he believed his blood pressure was between 110 and 160 millimeters, what would you say to him? (Enter your numerical answer to the nearest whole number.) He is correct O because 2.5 standard deviations below the mean would give him a blood pressure reading of millimeters, which is below O the range of 110 to 160 millimeters.
