z Scores. In Exercises 5-8, express all z scores with two decimal places. 5. Diastolic Blood Pressure of Females For the diastolic blood pressure measurements of females listed in Data Set 1 "Body Data" in Appendix B, the highest measurement is 98 mm Hg. The 147 diastolic blood pressure measurements of females have a mean of 70.2 mm Hg and a standard deviation of s = 11.2 mm Hg. = a. What is the difference between the highest diastolic blood pressure and the mean of the dia- stolic blood pressures for females? b. How many standard deviations is that [the difference found in part (a)]? c. Convert the highest diastolic blood pressure to a z score. d. Using the criteria summarized in Figure 3-6 on page 123, is the highest blood pressure sig- nificantly low, significantly high, or neither? T Body and exam measurements are from 300 subjects (first five rows shown here). AGE is in years, for GENDER = male and 0 female, PULSE is pulse rate (beats per minute), SYSTOLIC is systolic blood pressure (mm Hg), DIASTOLIC is diastolic blood pressure (mm Hg), HDL is HDL cholesterol (mg/dL), LDL is LDL cholesterol (mg/dL), WHITE is white blood cell count PLATE is platelet count (1000 cells/μL.), WEIGHT is weight (kg). HEIGHT is height (cm), WAIST is waist circumference (cm), ARM CIRC is arm circumference (cm), and BMI is body mass index (kg/m²). Data are from the National Center for Health Statistics.
