Two-sample tests
 Janoušková, Kateřina ; Hlávka, Zdeněk (advisor) ; Chochola, Ondřej (referee)
Two-sample T tests are described in this thesis. They are an im- portant method for testing hypotheses when samples have normal distribution. The main emphasis is laid on testing expected values when unknown variances are unequal. The test statistics used for testing hypotheses are presented and their null distribution is derived. In the beginning Student's distribution is de- scribed. The next chapters show how the Welch's and Satterthwaite's statistics are derived and it is described how to use them when testing hypotheses. Special paired test with missing samples is presented in the last chapter. 1
