Suppose a study was conducted concerning blood pressure of 65-year-old men with glaucoma. The average systolic blood pressure in 65-year-old men is 120mmHg. In the study, 150 65-year-old men with glaucoma are randomly selected and the sample mean systolic blood pressure was 140 mmHg and the sample standard deviation is 25 mmHg. Using a 0.05 significance level, you need to test the claim that this sample comes from a population with blood pressure that is significantly higher than 120 mmHg. What is the value of the test statistic you should use to test the given hypothesis?
