When discussing wait times, there are typically four figures of interest: arrival to triage (discussed in 3.1), triage to ER, wait to see a provider once in the ER, and overall arrival to provider wait times. The hospital would like to ensure that the overall arrival to provider wait time is less than 60 minutes. Column B has overall wait times for a random sample of 150 patients.
a) Using α = .05, conduct a one-tailed t test of the hypothesis that average wait time is less than 60 minutes. Use μ≤60 as your null hypothesis
b) What is the p value associated with your sample mean weight?
c) What conclusions can you draw from these results?
