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.

Transcribed Image Text: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.
Let p be the proportion of students that buy books.
O Let u be the mean number of books that college students
buy.
Let p be the proprotion of college students in the sample
that buy books.

State your conclusions:
We
do not
do
have strong evidence that the
o proportion of book purchased by college students in now
less than 35
O mean of book purchased by the sampled college students in
now less than 34
mean number of book purchased by college students in now
less than 35
O mean number of book purchased by college students in now
greater than 35
mean of book purchased by college students in now less
than 34
Is this evidence that the use of Open Educational Resources is
increasing?
Yes
No
