S6.5 From Table S6.1, A 2 = 0.308, D 4 = 1.777, D 3 = 0.223 S6.13 S6.19 = Total number of unsatisfied patients/Total number surveyed = 122/700 = 0.1743 Analyzing the p chart, we see that there are no points that fall out-side of the control limits. However, we can see that on day 6 the number of unsatisfied patients is approaching the upper limit. The hospital might note the meal served that day and monitor future patient feedback on those menu items.

S6.23 The chart indicates that there are no schools out of control. It also shows that 3 of 5 schools fall close to or below the process average, which is a good indication that the new math program has been taught as effectively at one school in the county as another. Whether or not the new math program is effective would require comparisons of this year’s test results with results from previous years (under the old program) or comparisons with national per-formance data.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
