In a completely randomized design, eight experimental units were used for each of the five levels of the factor. Consider the following ANOVA table.

Source of Variation Sum of Squares Degrees of Freedom Mean Square F p-value
Treatments 380 4 95 30.23 0.0000
Error 110 35 3.14
Total 490 39

(a)What hypotheses are implied in this problem?H0: 1 = 2 = 3 = 4 = 5 Ha: 1 2 3 4 5H0: 1 2 3 4 5 Ha: 1 = 2 = 3 = 4 = 5 H0: Not all the population means are equal. Ha: 1 = 2 = 3 = 4 = 5H0: 1 = 2 = 3 = 4 = 5 Ha: Not all the population means are equal.H0: At least two of the population means are equal. Ha: At least two of the population means are different.

(b)At the = 0.05 level of significance, can we reject the null hypothesis in part (a)? Explain.

Because the p-value > = 0.05, we cannot reject H0.

Because the p-value = 0.05, we can reject H0.

Because the p-value > = 0.05, we can reject H0.

Because the p-value = 0.05, we cannot reject H0.
