WebUsing the formula for the t-statistic, the calculated t equals 2. For a two-sided test at a common level of significance α = 0.05, the critical values from the t distribution on 24 degrees of freedom are −2.064 and 2.064. The calculated t does not exceed these values, hence the null hypothesis WebJul 3, 2024 · In the second table, the "Pooled" row gives the t test under the assumption that the variances of the two groups are approximately equal, which seems to be true for these data. The value of the t statistic is t = -1.45 with a two-sided p-value of 0.1645.
