3) A local bank has three branch offices. The bank has a liberal sick leave policy, and a vice- president was concerned with employees taking advantage of this policy.

Branch 1 17 21 19 15 18 Branch 2 12 14 11 13 11 Branch 3 15 19 22 17 20 (a) Do this data indicate a difference in branches? Use 0.05 level of significance. (b) Find the p-value for the test in (a) using F table. Comment whether it leads to the same се. conclusion in (a). (c) Write down the type I error in context for this question.
