Two Hospital Emergency Rooms Use Different Procedures for Triage of Their

question 65

Short Answer

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. Assume s_a = 2.1 minutes and s_b =2.92 minutes. What do you conclude about the waiting time for patients in the two hospitals, testing at α = .001?
