K A health journal found that 56.1% of college students who lived in coed dormitories consumed alcohol weekly (compared with 26.5% who lived in single-sex dormitories). A random sample of 180 students who live in coed dormitories was selected. Complete parts a through d below. a. What is the probability that more than 50% of the students in the sample consume alcohol weekly? The probability is 0.9505. (Round to four decimal places as needed.) b. What is the probability that less than 65% of the students in the sample consume alcohol weekly? The probability is 0.9920. (Round to four decimal places as needed.) c. What impact would changing the sample size to 110 have on the results in part a? Select the correct choice below and, if necessary, fill in the answer box to complete your choice. OA. The value of the probability increases. The new value of the probability is (Round to four decimal places as needed.) OB. The value of the probability decreases. The new value of the probability is (Round to four decimal places as needed.) OC. There is no change to the value of the probability.

A health journal found that 56.1% of college students who lived in coed dormitories consumed alcohol weekly (compared
with 26.5% who lived in single-sex dormitories). A random sample of 180 students who live in coed dormitories was
selected. Complete parts a through d below.
a. What is the probability that more than 50% of the students in the sample consume alcohol weekly?
The probability is 0.9505.
(Round to four decimal places as needed.)
b. What is the probability that less than 65% of the students in the sample consume alcohol weekly?
The probability is 0.9920
(Round to four decimal places as needed.)

c. What impact would changing the sample size to 110 have on the results in part a? Select the correct choice below
and, if necessary, fill in the answer box to complete your choice.
OA. The value of the probability increases. The new value of the probability is
(Round to four decimal places as needed.)
OB. The value of the probability decreases. The new value of the probability is
(Round to four decimal places as needed.)
OC. There is no change to the value of the probability.
