Show Work and Answer In Sentence FormSuppose the East Tennessean publishes an article stating that of those students who drink coffee the average number of cups of coffee students drink per week is 3 and we somehow know that the standard deviation is 2.5. Now, suppose you don’t believe this and you claim ETSU students drink on average more than 3 cups of coffee per week. You gather a SRS of 45 students who say they drink coffee and find that the average number of cups of coffee these students drink per week is 4.2. Is there evidence supporting your claim at significance level of 5 percent?
