2. A student claimed that the average grade in the night sections of Statistics was higher than the day sections. She used a sample of 35 students from night sections and found they had a mean of 78 with a standard deviation of 8. A sample of 32 day students had a mean of 75 with a standard deviation of 6. Is the student's hypothesis supported? (use α = .01)
