Please help with the last question

Blood pressure: A biood 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 fmmHg), for a sample of 10 adults. The following tabie presents the resuits. Use a \"PI-84 caicuiator to answer the following. Svsto lic Diastolic Systolic Diastolic 113 T? 116 70 123 77 133 91 119 69 112 75 118 88 10'? 71 130 3'6 110 74 Based on results published in the JUL-3minI of Human Hypertension (\"I Send data to Excel I") Part 1 Of4 9 Compute the leastsquares regression line for predicting the diastolic pressure from the systolic pressure. Round the slope and yintercept to at Feast four decimal places. A Regression line equation: y = .4743x + 20.?26 Compute the least-squares regression line for predicting the diastolic pressure from the systolic pressure. Round the slope and y-intercept to at least four decimal places. Regression line equation: y = .4748x + 20.726 Part 2 of 4 Is it possible to interpret the y-intercept? Explain. No , the x-values are all positive Part 3 of 4 X If the systolic pressures of two patients differ by 20 millimeters, by how much would you predict their diastolic pressures to differ? Round the answer to three decimal places. X Their diastolic pressures would differ by | 30.22 millimeters. Correct Answer: 9.496Part: 3 / 4 Part 4 of 4 Predict the diastolic pressure for a patient whose systolic pressure is 149 millimeters. Round the answer to one decimal place. The diastolic pressure is predicted to be millimeters
