For this problem, please state:

1) Null, Alternate Hypothesis, Type of test, & Level of significance.

2) Check the conditions

3) Compute the sample test statistic, draw a picture, and find the P-value.

4) State the conclusion about the Null Hypothesis.

5) Interpret the conclusion
Five years ago, the average math SAT score for students at one school was 475. A teacher wants to perform a hypothesis test to determine whether the mean math SAT score of students at the school has changed. The mean math SAT score for a random sample of 40 students from this school is 469. Do the data provide sufficient evidence to conclude that the mean math SAT score for students at the school has changed from the previous mean of 475? Perform the appropriate hypothesis test using a significance level of 10%. Assume that o=73
