Silway Travels organizes tours to a number of cities in Illinois. The manager of the company maintains a spreadsheet which is an annual record of airfares to different cities from Chicago. The contents of the spreadsheet can be analyzed to determine the difference in peak season and off-season airfares. The contents of the spreadsheet, in this case, represent .A) a survey
B) data
C) information
D) an analysis

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
