2) Calculate the average and standard deviation of the Avg Wait (min) column, so the average and standard deviation of the waiting times of hospitals. Shortly explain the meaning of your results.

3)The column contains the average waiting time at each hospital. In 2. you have calculated the average of these hospital-based waiting times. Now you are interested in the average wait time for a patient overall (so regardless of the hospital the patient was treated). Is it possible to calculate the average wait time of all individual patients in the state rather than for each hospital? If yes, explain how and then do so. If no, explain why it is not possible to do so.
