Her doctor is considering taking her off antihypertensive medications but wants to be fairly certain that her €œtrue€ DBP is less than 90 mm Hg. Use a statistical approach to answer this question. 

Hypertension

A hypertensive patient has been on antihypertensive medication for several years. Her physician wants to monitor her blood pressure via weekly measurements taken at home. Each week for 6 weeks she takes several blood pressure readings and averages the readings to get a summary blood pressure for the week. The diastolic blood pressure (DBP) results are shown in Table 6.15.

Table 6.15: Weekly mean DBP readings for an individual patient

 

The doctor takes the patient off antihypertensive medication and instructs her to measure her blood pressure for 3 consecutive weeks. The doctor will put the patient back on antihypertensive medication if her mean DBP over the 3 weeks is ‰¥90 mm Hg.
