The appropriate test to compare the number of customer complaints for one month to the usual number would be a one-sample t-test. This test compares the mean of the sample (the number of complaints in the one month) to a known value (the usual mean number of complaints) to determine if the difference is statistically significant. The other tests listed are not appropriate for this scenario.
