Question: A random sample of results of a standardized mathematics placement exam for two different campuses is as follows:
Campus Number Mean Std. Deviation
1 330 33 8
2 310 31 7
At the 0.05 significance level, we want to test the claim that the population mean score on Campus 1 is higher than on Campus 2.
