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. Systolic Diastolic 105 66 157 103 154 94 134 87 115 83 113 77 123 77 119 69 118 88 130 76 Based on results published in the Journal of Human Hypertension Send data to Excel Part 1 of 4 Compute the least-squares regression line for predicting the diastolic pressure ()) from the systolic pressure (x). Round the slope and ())-intercept to at least four decimal places. Regression line equation: y = 13.1324 + 0.5431X]. Alternate Answer: Regression line equation: y = 13.1324 +0.5431x. Part 2 of 4 X Is it possible to interpret the (V)-intercept? Explain. Yes , the x-values must be positive Correct Answer: No, the X-values must be positive.Is it possible to interpret the (y)interoept? Explain. thexvaluesmustbe- Correct RIISWBI': No, the xvalues must be positive. If the systolic pressures of two patients differ by 9 millimeters, by how much would you predict their diastolic pressures to differ? Round the answer to three decimal places. The diastolic pressure would differ by E] millimeters
