John was studying how far the UMN students travelled to take the class on campus. Let W be the distance travelled (measured in miles). A sample of size 25 was collected. He calculated the following statistics: John wanted to run a hypothesis test with the null and alternative hypothesis as below: Ho : μ = 5 Note that μ is the mean distance traveled by UMN students to come to campus. Please calculate the test statistic for the hypothesis test....

John was studying how far the UMN students travelled to take the class on campus. Let W be the distance travelled (measured in miles). A sample of size 25 was collected. He calculated the following statistics: W 3.8 Please calculate the 90% Confidence Interval for μ , the mean distance traveled by UMN students to come to campus. Suppose that the sample size 25 is NOT large enough for normal approximation (Hint: use t distribution). Note: You only need to...
