Form a Conclusion About Statistical Significance

question 52

Essay

Last year, the average math SAT score for students at one school was 475. The headmaster
introduced new teaching methods hoping to improve scores. This year, the mean math SAT
score for a sample of students was 481. Is there statistically significant evidence that the new
teaching method is effective? If the teaching method had no effect, there would be roughly a 3
in 10 chance of seeing such an increase. Does the result have statistical significance? Why or
why not? Does the result have practical significance?
