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 5 adults. Systolic Diastolic (x) (y) 157 103 154 94 134 87 115 83 113 77 1. Find the correlation coefficient, r (rounded to 3 decimal places.) decimal places. 2. Find the least-squares regression line for predicting the diastolic pressure from the systolic pressure. Round the slope and y-intercept values to 3 (y hat) D = 3. If the difference of the systolic pressure is 15 millimeters, what should be the expected difference of the diastolic pressure (rounded to 2 decimal places)
