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 (mmHg), for a sample of 10 adults. The following table presents the results. Use a TI-84 Plus calculator to answer the following. Systolic Diastolic 118 88 133 91 108 69 157 103 113 77 123 77 105 66 119 69 154 94 107 71
