At the start of the semester,a professor wants to monitor students who miss class.The professor implements a new attendance policy geared toward encouraging students to attend class every day.There are currently 150 registered students in the class,and each day the class takes a quiz that is just used to measure attendance.The number of quizzes that are turned in will serve as the measure of attendance.The quizzes are given at every class period and the class meets four times per week over a 15-week semester.Would creating a single p chart be useful for this situation with all students and the number of days missed on the same chart?
A)Yes,the number of students registered in the course will remain the same from day to day and the students are taking the course from the same professor.
B)No,it may be better to divide students up by the TA who is assigned to assist with the grading of the quizzes and make separate control charts for each TA's group of students.
C)No,separate charts should be made for the male and female students.
D)None of the above are appropriate reasons.

A p-chart is useful for monitoring the proportion of some characteristic (in this case, attendance) in a process, where the sample size remains constant. Since the number of registered students (150) remains the same throughout the semester, a single p-chart can effectively track attendance over time. The fact that all students are taking the course from the same professor ensures consistency in the attendance policy's application, making a single chart appropriate for monitoring purposes.
