Answer 1

I had done this using MINITAB 18 statistical software as follows-

MINITAB-stat-basic stat-two sample t test-give appropriate input-OK

As shown below,

It gives p-value =0.034 which is less than level of significance (0.05). Thus, we reject H0. There is significant evidence to show that student score lower on their final exam than midterm exam.
