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
130	76	110	74
116	70	108	69
133	91	105	66
112	75	157	103
107	71	154	94

Part 1 of 4

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

Part 2 : Is it possible to interpret the y- intercept? yes or no? are all the x - values postive or negaitve?
