Read, understand, and analyze the problems carefully. Work on the problem and follow the step by step procedures in solving it - from the null hypothesis to the recommendation. Round off to two decimal places. 1. A rural bank has four branches in a certain city. The bank president was anxious that employees were taking advantage of the bank's substantial sick leave policy; and he alleged that it might be associated with the branch where employees work. He requested each branch manager to submit the records of sick leave (in days) availed of randomly select employees the previous year. The table below shows the results. At a.01 alpha, is there significant difference on the mean number of sick leave availed of employees from the four branches?
