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, for a sample of 10 adults. The following table presents the results. Part: 0 / 4 Part 1 of 4 Part: 1/4 Part 2 of 4 Yes Part: 2/4 Compute the least-squares regression line for predicting the diastolic pressure from the systolic pressure. Round the slope and y-intercept values to four decimal places. Regression line equation: y=. Part 3 of 4 Is it possible to interpret the y-intercept? Explain. Systolic 157 154 134 115 113 millimeters. Part: 3/4 Diastolic 103 94 87 83 77 Their diastolic pressures would differ by Part 4 of 4 Based on results published in the Journal of Human Hypertension 4 X the x-values are all positive If the systolic pressures of two patients differ by 11 millimeters, by how much would you predict their diastolic pressures to differ? Round the answer to three decimal places. The diastolic pressure is predicted to be Systolic 123 119 118 130 116 Send data to Excel S Diastolic 77 69 88 76 70 millimeters. X Predict the diastolic pressure for a patient whose systolic pressure is 126 millimeters. Round the answer to one decimal place. X S V alb
