Blood pressure is measured in millimeters of mercury (mm Hg) and recorded with the systolic number first, followed by the diastolic number. You want to determine whether one's systolic blood pressure differs depending on whether its measured while standing or supine (lying flat on one's back). You gather 12 college students willing to participate and then measure their systolic blood pressures in both positions, 10 minutes apart: first standing (call this Condition 1), then supine (call this Condition 2). Their scores are below.

Participant Number	X1(Condition 1) Standing Blood Pressure	X2 (Condition 2) Supine Blood Pressure
1	132	136
2	146	145
3	135	140
4	141	147
5	139	142
6	162	160
7	128	137
8	137	136
9	145	149
10	151	158
11	131	120
12	143	150
