In 2015, the mean number of books that college students would buy was 35. With the use of Open Educational Resources, it is believed that this number has been decreasing. A recent sample of so college students found a sample mean of 34 books and a sample standard deviation of 5.1 books. We will perfrom a hypothesis test to determine if this is strong evidence that the mean number of books that college students purchase is decreasing and the use of Open Educational Resources is increasing. Define your variable. O Let u be the mean number of books that college students in the sample buy. O Let p be the proportion of students that buy books. O Let u be the mean number of books that college students buy. O Let p be the proprotion of college students in the sample that buy books. Write your hypotheses: Ho: ? 0 HA: ? 0 Find the P-value: Type your answer as a decimial rounded to three decimal places. Do not type a percentage or a percent sign. P-value= Using an a level of 5%, you should O Reject H, and Accept HA O Fail to Reject Ho O Accept H.
