WebAs is always the case, we need to start by finding a threshold value \(c\), such that if the sample mean is larger than \(c\), we'll reject the null hypothesis: That is, in order for our hypothesis test to be conducted at the \(\alpha=0.05\) level, the following statement must hold (using our typical \(Z\) transformation): WebWe calculate our test statistic as follows: t = difference of group averages standard error of difference = 7.34 (6.24×√(1/10+1/13)) = 7.34 2.62 = 2.80 t = difference of group averages standard error of difference = 7.34 ( 6.24 × ( 1 / 10 + 1 / 13)) = 7.34 2.62 = 2.80
