25 students are randomly chosen to evaluate an online learning application for a course assignment at College of Business at UNT. They are asked to rate the app on a scale from 1 to 5, with 1 being very bad and 5 being very good. The results of the survey reveal that the average rating is 4.22. Assume that the population standard deviation is known to be 0.5 based on similar studies in the past. The department is only interested in purchasing this application for that course if the true mean rating is more than 4. Significance level of 0.01 Assuming the calculated value of the test statistic is 2.73, what is the conclusion of testing whether the department should purchase this application? Use the significance level from Question 21. 25 students are randomly chosen to evaluate an online learning application for a course assignment at the College of Business at UNT.
