WebA t-test for two paired samples is a hypothesis test that attempts to make a claim about the population means ( \mu_1 μ1 and \mu_2 μ2 ). More specifically, a t-test uses sample information to assess how plausible it is for difference \mu_1 μ1 - \mu_2 μ2 to be equal to zero. The test has two non-overlaping hypotheses, the null and the ...

WebEntering a t table at 6 degrees of freedom (3 for n 1 + 3 for n 2) we find a tabulated t value of 2.45 (p = 0.05) going up to a tabulated value of 5.96 (p = 0.001). Our calculated t value exceeds these, so the difference between our means is very highly significant. Clearly, bacterium A produces significantly more biomass when grown on glucose than does … WebThe null hypothesis for the independent samples t-test is μ 1 = μ 2.So it assumes the means are equal.
