A sample of colored candies was obtained to determine the weights of different colors. The ANOVA table is shown below. It is known that the population distributions are approximately normal and the variances do not differ greatly. Use a 0.025 significance level to test the claim that the mean weight of different colored candies is the same. If the candy maker wants the different color populations to have the same mean weight, do these results suggest that the company has a problem requiring corrective action? Source: Treatment: 5 Error: Total: Ss: 0.085 0.348 0.433 DF: MS: 0.017 0.004 Test Stat, F: Critical F: P-Value: 2.7160 4.1334 0.0020 87 92 Should the null hypothesis that all the colors have the same mean weight be rejected? O A. Yes, because the P-value is less than the significance level. O B. No, because the P-value is less than the significance level. Oc. Yes, because the P-value is greater than the significance level. O D. No, because the P-value is greater than the significance level. Does the company have a problem requiring corrective action? O A. Yes, because it is not likely that the candies do not have equal mean weights. O B. No, because it is likely that the candies do not have equal mean weights. OC. No, because it is not likely that the candies do not have equal mean weights. O D. Yes, because it is likely that the candies do not have equal mean weights.

Contingency Table
A contingency table can be defined as the visual representation of the relationship between two or more categorical variables that can be evaluated and registered. It is a categorical version of the scatterplot, which is used to investigate the linear relationship between two variables. A contingency table is indeed a type of frequency distribution table that displays two variables at the same time.
Binomial Distribution
Binomial is an algebraic expression of the sum or the difference of two terms. Before knowing about binomial distribution, we must know about the binomial theorem.
