Set up the null hypothesis to determine whether there is a difference in the mean waiting time between the two hospitals.
Two hospital emergency rooms use different procedures for triage of their patients. We want to test the claim that the mean waiting time of patients is the same for both hospitals. The 40 randomly selected subjects from hospital A produce a mean of 18.3 minutes. The 50 randomly selected patients from hospital B produce a mean of 25.31 minutes. Sample standard deviations are sa = 2.1 minutes and sb = 2.92 minutes.
µa ? µb = 0
