A random sample of 10 night students was taken with a sample mean GPA of 3.5 and a standard deviation of 0.07. A random sample of 15 day students was taken with a sample mean GPA of 3.48 and a standard deviation of 0.04. Test the claim that the mean GPA of night students (N) is greater than the mean GPA of day students (μD) at a = 0.05. Assume that the data come from normal populations with unequal variances. Round your answers to three decimal places, and round any interim calculations to four decimal places.
