An education researcher wants to determine if there is a significant difference in the mean test scores between students who received private tutoring and those who did not. A random sample of 50 students was selected, and 25 of them received private tutoring while the other 25 did not. The mean test score for students who received tutoring is 80 out of 100 and for those who did not is 75 out of 100, with a common standard deviation of 10. Is there evidence to suggest that private tutoring has a significant effect on student test scores?
