Question:
Let X1,…,X9 be a random sample from a N(μ, 1) distribution, where μ is unknown. Suppose that we have observed the following values 16.34, 18.57, 18.22, 16.94, 15.98, 15.23, 17.22, 16.54, 17.54
We would like to decide between
a. Find a 90% confidence interval around X̅. Is μ0 included in the interval? How does this relate to our hypothesis test?
b. Define a test statistic to test the hypotheses and draw a conclusion assuming α = 0.1.
