Statistic and probability

4. Test Ho: H = 20.1 versus HA: H : M # 20.1, a simple random sample of size n= 11 is obtained from a population that is known to be normally distributed. a. . Construct a 99% confidence interval to test the hypothesis b. Compute the test statistic. c. Draw a t-distribution with the area that represents the P-value shaded. d. Approximate and interpret the P-value. e. If the researcher decides to test this hypothesis at the 0.1 level of significance, will the researcher reject the null hypothesis? Why
