Answer:
There is statistical evidence at 95% level to claim that students attend more than 2 classes per quarter
Step-by-step explanation:
Given that one instructor believes that students take more than 2 classes per quarter on average. Let X be the no of classes students take.

(Right tailed test at 5% significance level)

Mean difference = 
Std error = 
Test statistic t = mean diff/std error = 1.84
p value =0.039
Since p <0.05, we reject null hypothesis.
There is statistical evidence at 95% level to claim that students attend more than 2 classes per quarter
