One of the key quality characteristics in many service environments is that the variation in service time be reasonably small.Recently,a major amusement park company initiated a new line system at one of its parks.It then wished to compare this new system with the old system in place at a comparable park in another state.At issue is whether the standard deviation in waiting time is less under the new line system than under the old line system.The following information was collected: Assuming that it wishes to conduct the test using a 0.05 level of significance,the null hypothesis should be rejected since the test statistic exceeds the F-critical value from the F-distribution table.

The question mentions nothing about using an F-test or F-distribution, so it is not clear why the F-critical value is relevant. Additionally, the information provided is not sufficient to calculate any test statistic or compare it to a critical value. Therefore, we cannot conclude whether the null hypothesis should be rejected or not.
