A major airline recently began encouraging reservation agents to nap during their breaks. The table below lists the number of complaints received about each of a sample of 10 reservation agents during the 6 months before naps were encouraged and during the 6 months after the policy change. Conduct a hypothesis test to determine if the new napping policy reduced the mean number of customer complains about reservation agents. Be sure to state your hypotheses, test statistic, degrees of freedom (if applicable), p-value, and your conclusion based on the strength of the evidence.
