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. Use a TI-84

calculator to answer the following.

Systolic	Diastolic	Systolic	Diastolic
157	103	123	77
154	94	119	69
134	87	118	88
115	83	130	76
113	77	116	70

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.
