1 µ1 and µ2 are the means of the samples of equal size, while s.e. stands for the standard error for the mean; 2 95% confidence interval for difference in means; 3 t-statistic from the t-test on N = 70 degrees of freedom at the significance level α = 0.05; 4 p(α)-value is the probability under null hypothesis of equal means at the significance level α = 0.05; 5 F-statistic from the two-tailed F-test: the hypothesis that the two variances were equal is rejected if F-statistic > F-critical value; 6 F-critical value of the F distribution is with N1−1 and N2−1 degrees of freedom and significance level of α = 0.05; 7 F-prob means the probability under null hypothesis of equal variances.
