Last week, eldon’s professor suggested that he visit the writing center for extra on his papers because they were below average. eldon did not go to the center because he felt it would be a waste of time. eldon received a “d” on his next paper. this is an example of
a. social exchange theory
b. social construction of reality
c. self-fulfilling prophecy
d. ethnomethodology

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
