This pane displays the results of tests concerning the population from which the sample of Col_16 comes. The t-test tests the null hypothesis that the mean Col_16 equals .0 versus the alternative hypothesis that the mean Col_16 is not equal to .0. Since the P-value for this test is less than .05, we can reject the null hypothesis at the 95.0% confidence level. The sign test tests the null hypothesis that the median Col_16 equals .0 versus the alternative hypothesis that the median Col_16 is not equal to .0. It is based on counting the number of values above and below the hypothesized median. Since the P-value for this test is less than .05, we can reject the null hypothesis at the 95.0% confidence level. The signed rank test tests the null hypothesis that the median Col_16 equals .0 versus the alternative hypothesis that the median Col_16 is not equal to .0. It is based on comparing the average ranks of values above and below the hypothesized median. Since the P-value for this test is less than .05, we can reject the null hypothesis at the 95.0% confidence level. The sign and signed rank tests are less sensitive to the presence of outliers but are somewhat less powerful than the t-test if the data all come from a single normal distribution.
