In general, if the observed values and expected values of a goodness-of-fit test are not close together, then the test statistic can get very large and on a graph will be way out in the right tail.
Suppose an airline claims that its flights are consistently on time with an average delay of at most minutes. It claims that the average delay is so consistent that the variance is no more than minutes. Doubting the consistency part of the claim, a disgruntled traveler calculates the delays for his next flights. The average delay for those flights is minutes with a standard deviation of minutes.
If an additional test were done on the claim of the average delay, which distribution would you use?
