essay about protecting the environment - Variations of the t-Test: 2 Sample 2 tail 6 MINITAB output lets us know that MINITAB probably used only one or two more decimal places. The tSTAT in the output (T) is –, the exact value we got manually indicating that our calculation of the Satterthwaite approximation was good, and as we expected, the p value is highly significant, therefore as p hypothesis . In the two-sample t-test, the t-statistics are retrieved by subtracting the difference between the two sample means from the null hypothesis, which is is zero. Looking up t-tables (using spreadsheet software, such as Excel’s TINV function, is easiest), one finds that the critical value of t is 2. In statistics, Welch's t-test, or unequal variances t-test, is a two-sample location test which is used to test the hypothesis that two populations have equal means. It is named for its creator, Bernard Lewis Welch, and is an adaptation of Student's t-test, and is more reliable when the two samples have unequal variances and/or unequal sample sizes. thesis and dissertation accomplishedtm
