A study compared the number of tree species in unlogged forest plots to similar plots logged 8 years earlier.Independent random samples of both logged and unlogged plots were analyzed and the number of tree species wasrecorded. Tables 1 and 2 present the Shapiro-Wilk normality test for both types of forest plots and the IndependentSamples t-test results.

To perform this test, we assume that the population standard deviations of loggedand unlogged forest plots are equal.
