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, for a sample of

7

adults. The following table presents the results:

Systolic	Diastolic
133	91
154	94
115	83
116	70
134	87
157	103
123	77

Consider the least-squares regression line for predicting diastolic pressure (y) from systolic pressure (x).

Test Ho:1=0 versus H1: B10 .

Can you conclude that systolic blood pressure is useful in predicting diastolic blood pressure? Use the =0.10

level of significance.

...(yes or no),there ....(is or is not) enough evidence at the = 0.10 level of significance to conclude that systolic blood pressure is useful in predicting diastolic blood pressure. would you show me all steps you get the answer so that I can do similar questions, thank you.
