A city claims that service workers within city limits have a higher hourly rate than the average of all the surrounding cities. A sample of 86 workers show the city has an average of $9.56/hour. The surrounding city’s hourly wage for service workers is $8.07/hour with a variance of $14.55. Given the city was only able to get data from a small sample of workers, it is possible this difference is due to chance alone. Do a hypothesis test.
