1.(15) The dean of the Finance Department at Towson University wants to construct a p-chart for
determining whether the five faculty members teaching the course are in a state of control concerning the number of students who fail in the course. Accordingly, the chair sampled 400 final grades from last year for each instructor and computed the proportion of failures per instructor as 0.04, 0.02, 0.03, 0.0, and 0.01 respectively.
a). Compute the upper and lower standard control limits for this chart.
b). A newly hired adjunct taught a class of 50 students this semester and 4 students failed the class. Is the process still in control? Be sure to show all work for each problem.
