A study was aimed at assessing work schedule satisfaction levels, on a scale from 1 (very dissatisfied) to 7 (very satisfied), of hospital employees who were either job-sharers, full- time, or part-time. For a sample of twenty-five job-sharers, the mean satisfaction level was 6.60, for a sample of twenty-four full-time employees, the mean satisfaction level was 5.37; for a sample of twenty part-time employees, the mean satisfaction level was 5.20. The Fratio calculated from these data was 6.62.

(a) Set out the complete analysis of variance table.

(b) Test the null hypothesis of equality of the three population mean satisfaction levels.
