Ron McKeman, a University of Arkansas student who transferred from the University of Texas, believes that there is not enough time in between classes to walk from Carnall Hall to the Business Building. He is recommending to the Associated Student Government to extend the break between classes from 15 minutes to 20 minutes. He samples 45 students at the UA and finds the average time it takes to walk across campus is 16.55 minutes with a standard deviation of 3 minutes. Test Ron's belief that it takes more than 15 minutes to get across campus. The output on the following page may be helpful for answering these questions, a-.05 12. What hypotheses is Ron testing? 15 and HA > 15 15 and HAR 15 13 14 15 a b. C Ho Arkansas-Texas 50, HA MArkansas-Texas 0 20. HA HArkansas Texas O Ho Arkansas-Texas 8. Ho 20 and HA 20 d.
