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 123.00000 mm Hg and the standard devi is 14.29134 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 maan greater than 120 mm Hg Click the icon to view the data set of systolic blood pressure levels.
