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
= 121
and standard deviation
= 11.
If X = a systolic blood pressure score then
X ~ N(121, 11).
(a) Which answer(s) is/are correct? (Select all that apply.)
Kyle's systolic blood pressure is 175.
Kyle's systolic blood pressure is 1.75 times the average blood pressure of men his age.
Kyle's systolic blood pressure is 1.75 standard deviations above the average systolic blood pressure for men.
Kyle's systolic blood pressure is 1.75 above the average systolic blood pressure of men his age.
(b) Calculate Kyle's blood pressure. (Enter an exact number as an integer, fraction, or decimal.)
