An article reported the national market share of leading sellers of carbonated soft drinks. The pie chart and bar chart below display the values. a) Which is better for displaying the relative portions of market share? Explain. b) Is anything missing from these displays that might make them somewhat misleading? Other O B Other B E CAD a) Which display shows the relative portions of market share better? O A. The pie chart does because it shows the categories as portions of a whole. O B. The bar chart does because it shows the categories as portions of a whole. ° C. The bar chart does because it shows the categories in descending order by market share. D. The pie chart does because it shows the categories without spaces between them.

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
