Null Hypothesis of M&M colors with ANOVA
Not what you're looking for?
The weights (in grams) of four different colors of M&M candies are given below, along with the mean weight and variance of each color, and the variance of the sample means. Use a one-way ANOVA at the 0.025 significance level to test the null hypothesis that the different color M&M candies have the same mean weight.

F= 3.9031, and the critical value is 4.1528, so there is NOT sufficient evidence to reject the claim.
F= 3.5557, and the critical value is 4.0768, so there is NOT sufficient evidence to reject the claim.
F= 4.1410, and the critical value is 4.1528, so there is NOT sufficient evidence to reject the claim.
F= 3.9031, and the critical value is 3.7294, so there is sufficient evidence to reject the claim.
F= 4.1410, and the critical value is 4.0768, so there is sufficient evidence to reject the claim.
