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. e. State the decision base on the resulting computed value when compared to the critical value. f. Compute for the test statistic and compare with the critical value

Question

Instruction: Solve the following problem:

  1. 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.

e. State the decision base on the resulting computed value when compared to the critical value.

f. Compute for the test statistic and compare with the critical value.
