Daily Homework #15 - Anderson-Darling Test

Review questions:

1) What is the Anderson-Darling test? How is it conducted?

2) How is the Anderson-Darling test similar to the Kolmogorov-Smirnov test? How is it different?

2) Why must the critical values of the Anderson-Darling test be modified when the population mean and variance are estimated?

Computational exercise:

You will recall an earlier lecture review problem, in which Applied Statistics major Gracetta Squornshellous was investigating the research question: Are Alabama students really dumber than the national average? She obtained IQ test data on five students selected at random, as follows:

Compute the Anderson-Darling test statistic for Gracetta’s data. Use this to test the normality of the population.

SOLUTIONS:
AD = .31998
AD* = .256
