In order to check if blood pressure measurements change if one is sitting or standing, a study was conducted where systolic blood pressure of 35 patients were recorded while in sitting position and then again while standing. The comparison of systolic blood pressure in the two positions is an example of testing the difference between:

-Two means from independent populations

-Two population proportions

-Matched pairs from two dependent populations

-All of the above options are equally viable testing methods

    A random sample of size 13 is selected from men with hypertension. For each person, systolic blood pressure was measured right before and one hour after taking the medicine. The mean reduction of the blood pressures was 10.1 and the standard deviation of the difference was 11.2. In testing if there is sufficient evidence to conclude that the hypertension medicine lowered blood pressure, what is the p-value (round off to fourth decimal place)?
