Conduct a full hypothesis test and determine if the given claim is supported or not supported at the 0.05 significance level. Round all amounts and standard scores to two decimal places.
-In 1990, the average math SAT score for students at one school was 475. Five years later, a teacher wants to perform a hypothesis test to determine whether the average math SAT score of students at the school has changed. He picks a random sample of 60 students and obtains their mean math SAT score, which is 469. Test whether the claim that the average math SAT score at the school has dropped from 475 is supported or not
Supported. Assume that $\sigma = 73$
