Use an ANOVA with \( \alpha=.05 \) to determine whether there are any significant differences among the three treatment mes Numerator Degres of Freedom \( =6 \) Denominator Degrees of Freedom \( =16 \) \[ \triangle \Lambda \] Conclusion: Reject the null hypothesis; there are no significant differences among the three treatments. Fail to reject the null hypothesis; there are no significant differences among the three treatments. Fail to reject the null hypothesis; there are significant differences among the three treatments.
