Your results are statistically significant if … WebApr 23, 2024 · However, we will write T instead of Z, because we have a small sample and are basing our inference on the t distribution: (5.1.4) T = x ¯ − n u l l v a l u e S E = 135.9 − 100 82.2 30 = 2.39. If the null hypothesis was true, the test statistic T would follow a t distribution with df = n - 1 = 29 degrees of freedom.

WebDec 23, 2024 · Imagine you take a sample from X and a sample from Y and you do a t-test for difference between the two. If you repeat this sampling and testing many times, you will find that the t-test returns p > 0.05 in 95% of the cases. I.e. the null has not being rejected 95% of the time and this the "correct" outcome.

Set up hypotheses and determine level of significance. H 0: μ = 191 H 1: μ > 191 α =0.05. The research hypothesis is that weights have increased, and therefore an upper tailed test is used. Step 2. Select the appropriate test statistic.
