Park company manufactrues high technology testing instruments. The instruments are complex and not many units of any particular model are sold. The last unit of model MF-59 sold was the eight off of the assembly line. The labor cost for that unit was 2456.50 and required 614125 hours of labor. The fourth unit, produced last month required 72.25 hours of labor. Assuming that learning has been consistent for this product, how many hours did it take to produce the first unit

Aproduction line has three machines a, b, and c, with reliabilities of .96, .86, and .85, respectively. the machines are arranged so that if one breaks down, the others must shut down. engineers are weighing two alternative designs for increasing the line’s reliability. plan 1 involves adding an identical backup line, and plan 2 involves providing a backup for each machine. in either case, three machines (a, b, and c) would be used with reliabilities equal to the original three. a. compute overall system reliability under plan 1. (round your intermediate calculations and final answer to 4 decimal places.) reliability b. compute overall system reliability under plan 2. (round your intermediate calculations and final answer to 4 decimal places.) reliability c. which plan will provide the higher reliability? plan2plan1
