An independent-measures study with n = 6 in each sample produces a sample mean difference of 4 points and a pooled variance of 12.What is the value for the t statistic?
A)1
B)2
C)4/√2
D)4/√8

The t statistic is calculated using the formula $t = \frac{\text{mean difference}}{\sqrt{\frac{\text{pooled variance}}{n}}}$. Substituting the given values, $t = \frac{4}{\sqrt{\frac{12}{6}}} = \frac{4}{\sqrt{2}} = 2$.
