Hint: Is a statistics class' delivery type a factor in how well students do on the final exam? The table below shows the average percent on final exams from several randomly selected classes that used the different delivery types. Use the following output to evaluate weather at least one group mean is different from the rest at the 0.05 level of significance. 1 Hint: Link to Text Book Reject the null hypothesis, there is sufficient evidence to conclude that the at least one group mean is different from the rest. Fail to reject the null hypothesis, there is sufficient evidence to conclude that the at least one group mean is different from the rest. Fail to reject the null hypothesis, there is not sufficient evidence to conclude that the at least one group mean is different from the rest. Reject the null hypothesis, there is not sufficient evidence to conclude that the at least one group mean is different from the rest
