There is sufficient evidence to conclude that there is a significant difference among the three test preparation programs.O Reject Ho. There is not sufficient evidence to conclude that there is a significant difference among the three test preparation programs.O Do not reject Ho. There is not sufficient evidence to conclude that there is a significant difference among the three test preparation programs.

We need to conduct a Kruskal-Wallis test. The significance level is α=0.05.
