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 mmHg for a sample of 16 adults. The following table presents the results.

Compute the least-squares line for predicting the diastolic pressure from the systolic pressure. If the systolic pressures of two patients differ by 10 mmHg, by how much would you predict their diastolic pressures to differ? Predict the diastolic pressure for a patient whose systolic pressure is 125 mmHg. C. d.

The accompanying data represent the weights of various domestic cars and their gas mileages in the city for a certain model year. Suppose that we add Car 12 to the original data. Car 12 weighs 3 comma 3053,305 pounds and gets 1919 miles per gallon a) Compute the linear correlation coefficient with Car 12 included. The linear correlation coefficient with Car 12 included is r-? (Round to three decimal places as needed.) b) Recompute the linear correlation coefficient with Car 13 included. How did this new value affect your result? The linear correlation coefficient with Car 13 included is r-? t) Why does this observation not follow the pattern of the data?
