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 122.70000 mm Hg and the standard deviation is 15.35933 mm Hg. Assume that a simple random sample has been selected. Use a 0.10 significance level to test the claim that the sample is from a population with a mean greater than 120 mm Hg.

Question
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 122.70000 mm Hg and the standard deviation is 15.35933 mm Hg. Assume that a simple random sample has been selected. Use a 0.10 significance level to test the claim that the sample is from a population with a mean greater than 120 mm Hg.
Identify the test statistic. (Round to two decimal places as needed.) Identify the P-value. (Round to three decimal places as needed.) State the conclusion about the null hypothesis, as well as the final conclusion that addresses the original claim. the null hypothesis. There with a mean systolic blood pressure level greater than 120 mm Hg. sufficient evidence at the 0.10 significance level to the claim that the sample is from a population
