HypertensionA hypertensive patient has been on antihypertensive medication for several years. Her physician wants to monitor herblood pressure via weekly measurements taken at home.Each week for 6 weeks she takes several blood pressurereadings and averages the readings to get a summary bloodpressure for the week. The diastolic blood pressure (DBP)results are shown in Table 6.15.Table 6.15 Weekly mean DBP readingsfor an individual patientWeek Mean DBP Mean DBP (mm Hg) Week (mm Hg)1 89 4 842 88 5 823 81 6 89.5Mean 85.75sd 3.66 6.106 What is the probability that the sample mean will bewithin 1 unit of the population mean?6.107 Suppose we want to choose a large enough sampleso that the sample mean is within 1 unit of the populationmean 99% of the time.

Example#1: A researcher wishes to examine whether time of day (morning versus afternoon) affects the memory of older and younger participants. He obtains a sample of 40 older individuals and 40 younger individuals and gives them a passage to read. They are later given a test over the passage (scores on the test could range from O to 30). HaJf of the individuals are randomly assigned to read the passage and take the test in the morning, and the other half do so in the afternoon. The data are reported in the table below (the numbers represent mean test scores for each group; that is, "M" is mean). Morning Testing M= 15 Afternoon Testing Older Adults M=8 Younger Adults М- 16 М-20
