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. She thought that the tendency to take advantage depended on the branch at which the employee worked. To see if there were differences in the time employees took for sick leave, she asked each branch manager to sample employees randomly and record the number of days of sick leave taken during 1990. Ten employees were chosen, and the data are listed below. Does this data indicate a difference in branches? Use a level of significance of 0.05. Branch 1 15 20 19 Branch 2 11 15 11 Branch 3 18 19 23
