Answer 2

Null hypothesis: There is no difference between responses given by freshmen and sophomores. Test statistic: 7.4327. Critical value of chi square with 2 degrees of freedom for α=0.05 is 5.991. Reject the null. The opinions of freshmen and sophomores are significantly different. Freshmen seem to agree less and have no opinion more than the sophomores.
