people, and the standard deviation of the sample's waiting durations is minutes.Step-by-step explanation
Step 1.
The distribution is assumed to be normal in a single variance test. The null hypothesis and alternative hypothesis are both expressed in terms of the population variance. The sample variance can be a variable, with a sample size of people, a standard deviation of for waiting times, and population size of .
Therefore, the test statistic can be stated in the format of a one-variance test
where 
and 
.
A single variance test is the sort of test used here.
