Extended decision making is the type of consumer decision-making process thata) involves no conscious planning but rather a powerful and persistent urge to buy somethingb) is the most complex decision making behavior, which comes into play when a purchase involves unfamiliar, expensive, or infrequently bought productsc) requires a moderate amount of time for information gathering and searchd) is the creation and maintenance of a collection of products that satisfy a person's needs and wantse) requires very little search-and-decision effort and is practiced when buying low-cost and frequently purchased products.

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
