Allied Applications, a multinational commodities trading company, has recently introduced a new personnel evaluation system. Six months after implementing the system, Allied’s human resources director takes a random sample of 100 management level employees and 100 rank and file workers. Thirty percent of the management sample and 24% of the rank and file sample report that they are satisfied with the new system. Using a “no difference in satisfaction rates” null hypothesis, set up an appropriate hypothesis test. Use a significance level of 5%. Is the sample proportion difference statistically significant? Explain.
