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 125.88000 mm Hg and the standard deviation is 16.19283 mm Hg. Assume that a simple random sample has been selected. Use a 0.05 significance level to test the claim that the sample is from a population with a mean greater than 120 mm Hg.
