Background: The Worcester heart attack data provided below contains the systolic blood pressures of patients hospitalized for acute myocardial infarction (heart attack). This data is a protion of a larger data set compiled by Dr. Robert J. Goldberg of the Department of Cardiology at the University of Massachusetts Medical School between 1975 and 2001. The Center for Disease Control and Prevention (CDC) recommends that people maintain a systolic blood pressure of less than 140 mmHg.

Then perform an appropriate significance test to determine whether or not the systolic blood pressure of patients in this study is more than 140 mmHg.

1.State the null and alternative hypotheses.

2.Compute the test statistic and document how it was computed in the space provided below. Round all of the numbers used in the calculation to 2 decimal places.

3.Compute the p-value. Provide the name of the probability distribution used and the values of the parameters you entered into the calculator and report the p-value rounded to 4 decimal places

4.Interpret the results of the test. Is there statistically evidence that the average systolic blood pressure of the patients in the study was above 140 mmHg? Does this result have any practical significance?
