3 2 3 1 3 46 Pacific Manufacturing Company has a 2.5 HP industrial pump which, in the recent past, has shown some problems. This has interrupted the production line and has led to unexpected down time of the production line. The maintenance department is considering to take preemptive measures to face this problem. Table 3.a shows the frequency of breakdown of the pump over the past year (52 weeks), which was taken from the company's maintenance records.
