In a Two-Tailed Pooled-Variance T-Test (Equal-Variances T-Test), the Null and Alternative

In a two-tailed pooled-variance t-test (equal-variances t-test), the null and alternative hypotheses are exactly the same as in one-way ANOVA with: $\begin{array}{|l|l|}\hline \text { A. } & \text { exactly one treatment. } \\\hline \text { B. } & \text { exactly two treatments. } \\\hline \text { C. } & \text { exactly three treatments. } \\\hline \text { D. } & \text { any number of treatments. } \\\hline\end{array}$
