2. To monitor performance, the radiology department at Guelph General Hospital is interested in setting standards for the time patients spend waiting when brought in for x rays from the emergency department. They want to track performance and are proposing setting up process control chart(s) for wait times. They tracked six different patients for five days and the data is presented below. The time is in minutes spent waiting. Day 1 2 3 4 5 6 Monday 14 13 20 18 17 21 Tuesday 22 21 18 17 18 17 Wednesday 16 14 17 20 15 22 Thursday 13 19 Friday 15 16 96 20 21 18 21 == 14 18 17 22 a) Calculate the appropriate upper and lower control limits for the average time spent waiting. b) Is the process currently in control? c) The hospital hired a new tech and their wait times for 3 days are evaluated? Is the new tech doing a job consistent with that of the others? Day Monday 1 2 3 4 5 6 18 Tuesday 14 22 24 21 24 23 26 20 21 22 21 19 Wednesday 13 14 16 19 15 15 20
