Compute the least-squares regression line for predicting the diastolic pressure from the systolic pressure. Round the slopeand y-intercept to at least four decimal places. Compute the least-squares regression line for predicting the diastolic pressure from the systolic pressure. Round the slopeand y-intercept to at least four decimal places.Regression line equation: y = Blood pressure: A blood pressure measurement consists of two numbers: the systolic pressure, which is the maximum pressuretaken when the heart is contracting, and the diastolic pressure, which is the minimum pressure taken at the beginning of theheartbeat. Blood pressures were measured, in millimeters of mercury (mmHg), for a sample of 10 adults. The following tablepresents the results.

Consider a linear regression model for the decrease in blood pressure (mmHg) over a four-week period with muy=2.8+0.8x and standard deviation chi=3.2. The explanatory variable x is the number of servings fruits and vegetables in a calorie-controlled diet. Explain clearly what this slope says about the change in the mean of y for a change in x.
The flow rate in a device used for air quality measurement depends on the pressure drop x (inches of water) across the device's filter. Suppose that for x values between 5 and 20, these two variables are related according to the simple linear regression model with true regression line y = -0.11 + 0.097x. (a.1) What is the true average flow rate for a pressure drop of 10 in.?(a.2) A drop of 15 in.?(b) What is the true average change in flow rate associated with a 1 inch increase in pressure drop?(c) What is the average change in flow rate when pressure drop decreases by 5 in.?
