Problem 3 You’re a healthcare engineering consultant and you’re analyzing the emergency room design at Pawhuska Hospital, Inc. Below you’ll find sample data for the waiting time (in minutes) of non-critical patients entering the emergency room. a. The hospital administrator wants to make the claim that average waiting time for non-critical patients is less than an hour. What is your opinion of that claim using the p-value approach? (note that you’d probably reject any null hypothesis if p-value < 0.1) b. In fact, you believe that at least a third of the non-critical patients arriving to the emergency room wait more than an hour. Test your claim with the critical value approach and 95% confidence.

Problem 3
You’re a healthcare engineering consultant and you’re analyzing the emergency room design at Pawhuska Hospital, Inc. Below you’ll find sample data for the waiting time (in minutes) of non-critical patients entering the emergency room.
a. The hospital administrator wants to make the claim that average waiting time for non-critical patients is less than an hour. What is your opinion of that claim using the p-value approach? (note that you’d probably reject any null hypothesis if p-value < 0.1)
b. In fact, you believe that at least a third of the non-critical patients arriving to the emergency room wait more than an hour. Test your claim with the critical value approach and 95% confidence.
