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, for a sample of 16 adults. The following table presents the results. Systolic * Diastolic 134 87 115 33 113 77 123 77 119 69 118 88 130 76 118 70 133 91 112 75 107 71 110 74 108 69 105 66 157 103 154 94 Note that these are the same data used in a previous question, so you may simply continue your work for this question. Compute the least-squares line for predicting the diastolic pressure from the systolic pressure. What is the value of the slope? Round the value to four decimal places
