please answer all question.

QU ESTIDN 1 A random sample of employees were 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. (4 marks) b) Given the betweengroup yanance is 727.925 and total sum of square is 2323. Hence, compute the value of test statistic for the above data. (3 marks) c) At the 0.05 signicance level, test the claim that there is a difference in mean ages for three types of stores at the mall. (4 marks)
