Hypothesis Testing Paired T Test. Before and after t 2 0038 df 3 p value 0 1388 alternative hypothesis. The paired sample t test has four main assumptions.
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. μ1 μ2 the two population means are not equal. The dependent variable must be continuous interval ratio.
True difference in means is not equal to 0 95 percent confidence interval.
We will perform the paired samples t test with the following hypotheses. A t test for two paired samples is a hypothesis test that attempts to make a claim about the population means mu 1 μ1. The dependent variable must be continuous interval ratio. The observations are independent of one another.
