The sample consisted of 50 night students, with a sample mean GPA of 3.02 and a standard deviation of 0.08, and 25 day students, with a sample mean GPA of 3.04 and a standard deviation of 0.06. The test statistic is:

The test statistic is t= -0.90.

Step-by-step explanation:

Since we have given that

n₁ = 50

n₂ = 25

So, s would be

So, the value of test statistic would be

Hence, the test statistic is t= -0.90.

  n=   0.0000 - 0.3750 i  

  n=   0.0000 + 0.3750 i
