A two-sample t test should be used to compare the means of two independent groups, in this case the two course sections. The one-sample t test is used to compare the mean of a single group with a known population mean. The matched-pairs t procedure is used to compare the means of two related groups, such as before and after an intervention in the same group. None of the above options are appropriate for comparing the academic performance of two different course sections.
