[b] Instruction: Solve the following problem:

Records show that the performance of male college students in Mathematics in terms of final grade is 5% higher than in female college students with a corresponding standard deviations of 4.35% and 3.97%, respectively. A mathematics instructor verifies this information by having the final grades. There are 80 students, consisting of 44 females and 36 males. The following statistics are shown:

Sex	Average Final Grade
Male	93.45%
Female	87.42%

Can the mathematics instructor say that the difference between the average final grades obtained by the males and females is higher than 5%? Use 5% level of significance.

b. Determine the level of significance and the direction of test.
