QUESTION 1

A random sample of employees was selected from three different types of stores at the mall and their ages were recorded. Assume that the assumptions for the parametric test are met. The data were analyzed and the result is shown below.

a) Calculate the sum of squares between groups.

b) Given the between-group variance is 727.925 and the total sum of squares is 2823. Hence, compute the value of the test statistic for the above data.

c) At the 0.05 significance level, test the claim that there is a difference in mean ages for three types of stores at the mall.
