Yellowstone Park Medical Services (YPMS) provides emergency health care for park visitors. Such health care includes treatment for everything from indigestion and sunburn to more serious injuries. Suppose a recent issue of Yellowstone Today (National Park Service Publication) indicated that the average number of visitors treated each day by YPMS was 25.8, and the estimated standard deviation was 8.013738. The distribution of numbers treated is approximately mound-shaped and symmetrical. For a 10-day summer period, the following data show the number of visitors treated each day by YPMS: Day 1 2 3 4 5 6 7 8 9 10
Number treated 34 10 33 33 30 18 29 28 18 25
Make a control chart for the daily number of visitors treated by YPMS, and plot the data on the control chart. Do the data indicate that the number of visitors treated by YPMS is "in control"? Explain your answer.
