To test H0:=100 versus H1:100, a simple random sample of size n=15

is obtained from a population that is known to be normally distributed. Answer parts (a)-(e).

A) If x=104.2 and s=9.2, compute the test statistic.

B) If the researcher decides to test this hypothesis at the =0.01level of significance, determine the critical values.

C) Draw a t-distribution that depicts the critical regions.

D) Will the researcher reject the null hypothesis?

E) Construct a 99% confidence interval to test the hypothesis.
