Based on the computations for the within- and between-sample variation, develop the ANOVA table and test the appropriate null hypothesis using alpha= 0.05. Use the p-value approach.
A) Since p-value = 0.0678 > 0.05 reject H0 and conclude that at least two population means are different.
B) Since p-value = 0.000136 < 0.05 reject H0 and conclude that at least two population means are different.
C) Since p-value = 0.0678 > 0.05 accept H0 and conclude that all population means are the same.
D) Since p-value = 0.000136 < 0.05 accept H0 and conclude that all population means are the same.
