You're the operations manager at a regional hospital and your management has set the goal that no one should wait more than 3 minutes to see a nurse in the Emergency Room. You've collected 40 samples of the average wait times at five different times during the day over 40 days as shown below. a. construct an x-bar chart for this data. Is the process in control? b. using 3 minutes as the upper tolerance limit and zero as the lower tolerance...

I ONLY NEED HELP WITH PART OF PART "B" I've figured out the test statistic is -1.73 and the degrees of freedom are 5. However, I'm having a hard time finding the P value via the chart (which I'm required to learn how to do).I think the chart immediately bellow this is the one used to find the p-value. However, I know at least one (or more) of the charts bellow is what's used. Please let me know which chart...
