3.3.2. Independent Samples *t*-Test

The F-test recognized that there was no significant difference in the variance of the volume leakage between the two. Therefore, in the *t*-test, under the condition of equal variances, the calculated t-statistic value of 10 Pa was −1.077, with a two-tailed *p*-value = 0.296 > 0.05. The calculated t-statistic value of 25 Pa was −1.467, with a two-tailed *p*-value = 0.160 > 0.05; therefore, the null hypothesis cannot be rejected.
