Coffee and blood pressure. A scientist suspects that coffee increases blood pressure. So, he measures the systolic blood pressure of six random patients and then measures it again 30 minutes after they drink a single cup of caffeinated coffee. The results are tabulated below. Test the claim that coffee causes an increase in blood pressure. Before Coffee 112 114 100 119 120 115 After Coffee 112 119 102 123 121 118 (a) Why are these paired data? O The after and before rows are the same size. O Each column contains data from the same patient. Most of the 'After Coffee' values are smaller than the corresponding 'Before Coffee' values. This table does not have paired data; there is no clear relationship between the data in each column. (b) Write the hypotheses in symbols. Note that this problem uses Hdiff=before-after instead of "diff-after-before so be careful. OH.: Hdiff-before-after = 0 Ha: Hdiff=before-after 0 O Ho: Hdiff-before-after = 0 Ha: Hdiff=before-after = 0
