Problem 7
You’re a healthcare engineering consultant and you’re analyzing the emergency room design at
Pawhuska Hospital, Inc. In "DATA" below you’ll find sample data for the waiting time (in
minutes) of non-critical patients entering the emergency room. You have reason to believe that
the standard deviation of non-critical patient waiting time is more than 20 minutes. Test that
belief with the p-value approach using Excel.
