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, for a sample of 6 adults. The following table presents the results. Systolic Diastolic 134 87 115 83 113 77 123 77 119 69 118 88 Send data to Excel The least-squares regression line =y=+b0b1x+42.08470.3165x and =Σ−xx2283.3333 are known for this data. Use the P -value method to test =:H0β10 versus >:H1β10 . Can you conclude that systolic blood pressure is useful in predicting diastolic blood pressure? Use the =α0.05 level of significance and the TI- 84 calculator.

Send data to Excel
The least-squares regression line
=y=+b0b1x+42.08470.3165x
and
=Σ−xx2283.3333
are known for this data. Use the
P
-value method to test
=:H0β10
versus
>:H1β10
. Can you conclude that systolic blood pressure is useful in predicting diastolic blood pressure? Use the
=α0.05
level of significance and the TI-
84
calculator.
