Blood Pressure

There is a considerable variation in blood pressure during a day. The systolic blood pressure reading of a patient of high blood pressure has a normal distribution with a mean of 160 mm mercury and a standard deviation of 20 mm. The variable SBP has a sample of 100 values randomly generated from the normal distribution described above. Every five observations are grouped, and the group number is assigned to each group, which is recorded in the variable GROUP.
