WebUsing a two-tailed t-test with alpha level of 0.05 and degrees of freedom (df) of 16 (df = n1 + n2 - 2), we can find the critical t-value from a t-distribution table or calculator to be ±2.131. Since the calculated t-value of -2.90 is outside the range of the critical t-values of ±2.131, we reject the null hypothesis and conclude that there ...
