A glass factory makes a continuous ribbon of glass by pouring a continuous stream of hot, liquid silicon on a lake of molten tin. The liquid silicon spreads out evenly on the tin and then cools into glass. It is a process that must continue uninterrupted 24 hours a day, so adjustments to equipment and materials are ongoing. Assume that inspectors work eight-hour shifts, watching the glass ribbon as it flows from the lake of tin, marking and counting the number of defects on the new glass. The number of defects identified by the inspectors for one 24-hour period is shown below. Hour 1 3 4 6. 8. 9. 10 11 12 Defects 43 40 42 40 38 39 36 38 44 41 45 42 Hour 13 14 15 16 17 18 19 20 21 22 23 24 Defects 40 37 39 39 43 40 42 42 38 41 38 37 a.
