Systolic blood pressure levels above 120 mm Hg are considered to be high.For the

100 systolic blood pressure levels listed in the accompanying data set, the mean is

121.44000 mm Hg and the standard deviation is 17.10120 mm Hg. Assume that a simple random sample has been selected. Use a 0.01 significance level to test the claim that the sample is from a population with a mean greater than 120 mm Hg.
