Hope this helps!

The p -value for the hypothesis test is 0.003.

Step-by-step explanation:

In this case, a paired t-test would be used to determine whether the drug  increases blood pressure.

The hypothesis can be defined as follows:

H₀: The drug has no effect on blood pressure, i.e. d = 0.

Hₐ: The drug increases blood pressure, i.e. d > 0.

The information provided is:

The test statistic is:

The degrees of freedom of the test is:

The p-value of the test is:

*Use a t-table.

Thus, the p -value for the hypothesis test is 0.003.
