Question

5. A physician suspects that the office balance beam scale may be giving consistently higher readings for the weights of patients than those obtained on the small bathroom scales that the patients use in their homes. To test this hypothesis, the physician asks 10 patients to record their weights when they are fully clothed before leaving home. They are weighed fully clothed as soon as they get to the office. The following observations are obtained: 150 147 203 171 129 110 179 132 138 210 153 146 207 173 112 181 132 139 213 where X: home weight and Y is office weight (both in pounds). a) Test the appropriate hypotheses and report your findings. Let a 0.05. b) Construct a 95% confidence interval. Compare test results and the confidence interval.
