P-Chart: Temporary Work Jobs for the homeless! A philanthropic foundation bought a used school bus that stops at homeless shelters early every weekday morning. The bus picks up people looking for temporary, unskilled day jobs. The bus delivers these people to a work center and later picks them up after work. The bus can hold 75 people, and it fills up every morning. Not everyone finds work, so at 11 A.M. the bus goes to a soup kitchen where those not finding work that day volunteer their time. Let us view each person on the bus looking for work as a binomial trial. Success means he or she got a day job. The random variable r represents the number who got jobs. The foundation requested a P-Chart for the success ratios. For the past 3 weeks, we have the following data.
Make a P-Chart, list any out-of-control signals, and interpret the results.
