Hypothesis Testing Paired T Test. And so we run a paired t test and the manager wants to test if their times when wearing harpo s are significantly lower than their times when. And so as you can imagine here in this example we are dealing with a paired t test.
A t value of zero indicates that your sample results match the null. A t test for two paired samples is a hypothesis test that attempts to make a claim about the population means mu 1 μ1. Mean of the differences 43.
We will perform the paired samples t test with the following hypotheses.
In an unpaired t test the variance between groups is assumed to be equal. μ1 μ2 the two population means are not equal. A t value of zero indicates that your sample results match the null. The paired sample t test has four main assumptions.
