Blood pressure: A blood pressure measurement consists of two numbers: the systolic pressure, which is the maximum pressure taken when the heart is contracting, and the diastolic pressure, which is the minimum pressure taken at the beginning of the heartbeat. Blood pressures were measured, in millimeters of mercury, for a sample of 7 adults. The following table presents the results. Systolic 116 107 105 113 118 133 110 Diastolic 70 71 66 77 88 91 74 Construct a 99% confidence interval for the slope. Round the answers to at least four decimal places.
