a. the data do not provide sufficient evidence to reject the h0; thus, we can conclude that the mean number of parties attended by fraternity and sorority members is higher than those attended by unaffiliated students.
b. the data do not provide sufficient evidence to reject h0; thus, we cannot conclude that the mean number of parties attended by fraternity and sorority members is higher than those attended by unaffiliated students.
c. the data provide sufficient evidence to reject h0; thus, we can conclude that the mean number of parties attended by fraternity and sorority members is higher than those attended by unaffiliated students.
d. the data provide sufficient evidence to reject the h0; thus, we cannot conclude that the mean number of parties attended by fraternity and sorority members is higher than those attended by unaffiliated students.
