4. A sample size of n=25 is selected from a normal population with mean of 61, * = 56 and σ=12. 5. It is assumed that the mean systolic blood pressure is = 120 mm Hg. In the Honolulu Heart Study, a sample of people had an average systolic blood pressure of 130.1 mm Hg with a standard deviation of 21.21 mm Hg. Is the group significantly different (with respect to systolic blood pressure!) from the regular population?
