Recent Statistical problem that occurred at my job facility.

Fleet consists out of 32 trains each needs to get radio communication equipment upgrade. During testing period approximately every 4^th devices came defective from factory due to limited production and tight schedule. And by contract company has to keep 20% extra devices as spare parts. Question was given that 40 radio devices were purchased is it enough to convert whole fleet of 32 vehicles during next testing phase, accounting for possible defects from factory?

I am currently working in company that manufactures and maintenance train and light jet planes. Because of limited production nature and specifics of industry a lot of devices and parts are manufactured in limited quantities and are unique for site and application. During testing, installation, and commissioning periods it’s important to know probability of getting defective equipment, which helps to calculate amount of spare parts needed to sustain fleet operation. Statistics helps at work as well as in life. Just looking up data for car crushes occurred I make a decision on whether to take a road trip or just fly. Card problems from beginning of semester improved my poker skills and increased my financial wellbeing.
