Listed below are drive-through service times (seconds) recorded at McDonald's during dinner times (from Data Set 25 "Fast Food" in Appendix B). Assuming that dinner service times at Wendy's have standard deviation σ = 55.93 sec, use a 0.01 significance level to test the claim that service times at McDonald's have the same variation as service times at Wendy's. Should McDonald's take any action?

Test the given claim. Identify the null hypothesis, alternative hypothesis, test statistic, P-value, or critical value(s), then state the conclusion about the null hypothesis, as well as the final conclusion that addresses the original claim. Assume that a simple random sample is selected from a normally distributed population.
