Solve the problem.A mother wishes to distribute 11 pieces of candy among her three children (Abe, Betty, and Cindy) based on the number of hours each child spends doing chores around the house. Using a certain apportionment method, she has determined that (based on 703 minutes work for Abe, 243 minutes work for Betty, and 54 minutes work for Cindy) that Abe is to get 8 pieces of the candy, Betty is to get 3 pieces, and Cindy is to get 0 pieces. However, just before she hands out the candy, she discovers that she forgot to include 86 minutes of work that Abe did, 12 minutes of work that Betty did, and 2 minutes of work that Cindy did. When she reapportions the 11 pieces of candy using the corrected times and using the same apportionment method, Abe ends up with 8 pieces, Betty with 2
pieces, and Cindy with 1 piece. This is an example of A. the Alabama paradox. B. the new states paradox. C. a violation of the quota rule. D. the population paradox. E. none of these
