Paired Samples T Test Null Hypothesis. µ 1 is not equal to µ 2. Null hypothesis for paired sample t test 1.
In the case of the paired samples t test the null hypothesis is that the two means are equal. Null hypothesis for paired sample t test 1. μ 1 μ 2 the two population means are equal the alternative hypothesis can be either two tailed left tailed or right tailed.
A paired samples t test always uses the following null hypothesis.
Like many statistical procedures the paired sample t test has two competing hypotheses the null hypothesis and the alternative hypothesis. In the example above we use a t test for independent means to try and disprove the null hypothesis. The null hypothesis h0 states that there is no significant difference between the means of the two groups. This null hypothesis is tested against one of the following alternative hypotheses depending on the question posed.
