Henry had his blood pressure tested, and he was told that his systolic blood pressure is 130 mm Hg and his diastolic blood pressure is 85 mm Hg. Based on these readings, Henry's blood pressure would be classified as • normal • prehypertensive stage 1 hypertension • stage 2 hypertension

i. A normal systolic blood pressure is one where the average reading is 120 or below. A doctor believes that a patient has high blood pressure i.e. has an average systolic blood pressure reading greater than 120. What are the null and alternative hypotheses for this scenario? a. H0: mu > 120 H1: mu = 120 b. H0: mu = 120 H1: mu < 120 c. H0: mu = 120 H1: mu > 120 d. H0: xbar = 120 H1: xbar > 120

Kyle's doctor told him that the z-score for his systolic blood pressure is 1.75. Which of the following is the best interpretation of this standardized score? The systolic blood pressure (given in millimeters) of males has an approximately normal distribution with mean μ = 125 and standard deviation σ = 14. If X = a systolic blood pressure score then X ~ N(125, 14). (a) Which answer(s) is/are correct? (Select all that apply.) Kyle's systolic blood pressure is 1.75 above the average systolic blood pressure of men his age. Kyle's systolic blood pressure is 1.75 times the average blood pressure of men his age. Kyle's systolic blood pressure is 175. Kyle's systolic blood pressure is 1.75 standard deviations above the average systolic blood pressure for men. (b) Calculate Kyle's blood pressure.
