Question

In some firefighting organizations, you must serve as a firefighter for some period of time before you can become part of the emergency medical service (EMS) arm of the organization. Does that mean EMS workers are older, on average, than traditional firefighters? Use the data shown and α = .05 to test whether EMS workers are significantly older than fire fighters. Assume the two groups are independent and you do not want to use a t test to analyze thedata.
