Daily Homework #15 - Kolmogorov-Smirnov Test

Review questions:

1) What is the Kolmogorov-Smirnov test? How is it conducted?

2) Why must the critical values of the Kolmogorov-Smirnov 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 Kolmogorov-Smirnov test statistic for Gracetta’s data. Use this to test the normality of the population.

SOLUTIONS:
KS = .2389; p-value>.20
