**Question:**Two samples, each with \( n = 16 \) scores, produce an estimated standard error of 4 points and a \( t \) statistic of \( t = 2.00 \). What is the sample mean difference?**Options:**- ○ 4- ○ 16- ○ 8- ○ 2**Explanation:**To find the sample mean difference, you can use the formula for the \( t \) statistic:\[ t = \frac{\text{mean difference}}{\text{standard error}} \]Given that the \( t \) statistic is 2.00 and the standard error is 4, you can solve for the mean difference as follows:\[ 2.00 = \frac{\text{mean difference}}{4} \]\[\text{Mean difference} = 2.00 \times 4 = 8\]Therefore, the sample mean difference is 8.
