Among 157 African-American men, the mean systolic blood pressure was 146 mm Hg with a standard deviation of 27. We wish to know if on the basis of these data, we may conclude that the mean systolic blood pressure for a population of African- American is greater than 140. Use a=0.01.

Confidence Intervals

When we calculate intervals in probability and statistics, it can be simply termed as finding out a confidence interval. The confidence interval is usually calculated from the data set which is observed. The value of the parameter that needs to be calculated is present here only.

Question

Conduct hypothesis testing using traditional way and the p-value of the following problem.

1. Among 157 African-American men, the mean systolic blood
pressure was 146 mm Hg with a standard deviation of 27. We
wish to know if on the basis of these data, we may conclude that
the mean systolic blood pressure for a population of African-
American is greater than 140. Use a=0.01.

Hello. Could anyone help me on this question? I have tried it four times and only one attempt left. What I am confusing is that some choice are not individual and variables.

A group of 250 patients was randomly split into two groups of 125 patients. The first group of 125 patients was given treatment A, and 72 of them improved their condition. The second group of 125 patients was given treatment B, and 60 of them improved their condition. Perform a hypothesis test to investigate whether there is evidence of a difference between the two treatments. What is the p-value of the test?
