[16 pоints оn Grаdescоpe] The UA аdministrаtion claims that on average undergraduates spend 22.1 hours per week studying. We want to test if this is accurate. We sample 213 students and find that the average of the time/per week they spend studying is 22.9 hrs/week with a samplestandard deviation of 7.2 hrs/week. a. State the null and alternative hypotheses and define the test statistic to be used. You should define any parameters you introduce. b. Suppose that we use a significance level of α=10%{"version":"1.1","math":"α=10%"}. Find the rejection region. SHOW ALL YOUR WORK c. What conclusion do you make based on the data? Explain your answer.
