Question
A mathematics professor one to determine whether there is a different in the final average just between the past two semester (semester 1 and semester 2) of his business is statistics classes. For a random sample of 16 students from semester 1, the mean of the final averages was 75 with a standard deviation of 4. For a random sample of 9 students from semester 2, the mean was 73 with a standard deviation of 6.
Choose the correct answer
![If the final averages from semesters I and 2 are assumed to be normally distributed
with equal variances, the appropriate set of hypotheses is
