The systolic blood pressure (given in millimeters) of males has an approximately normal distribution with mean ? = 130 and standard deviation ? = 14. (a) Calculate the z-scores for the male systolic blood pressures 125 and 135 millimeters. (Round your answers to two decimal places.) 125 mm z = 135 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 125 and 135 millimeters, what would you say to him? (Enter your numerical answer to the nearest whole number.) He is _______or because 2.5 standard deviations below the mean would give him a blood pressure reading of ________ millimeters, which is ________ the range of 125 to 135 millimeters.
