Manufacturing companies strive to maintain productionconsistency, but it is often difficult for outsiders to tell whether they have succeeded. Consider a company that makes a certain brand of candy claims that 10% of the candies it produces are green and that bags are packed randomly. Their production controls can be checked by sampling bags of candies. Suppose bags containing about 240 candies are opened and the proportion of green candies is recorded. Complete parts a through c. a) Explain why it's appropriate to use a Normal model to describe the distribution of the proportion ofgreen candies they might expect in the 240-candy bagIt's appropriate to use a Normal Model because np = and nq = which are "both greater than or equal to 10" or "at least one is greater than or equal to 10" (choose the right answer here)b) Use the 68−95−99.7 Rule to describe how this proportion might vary from bag to bag. About 68% of the bags will have between ___% and % green candies.(Use ascending order. Round to one decimal place asneeded.)About 95% of the bags will have between ___% and % green candies(Use ascending order. Round to one decimal place asneeded.)About 99.7% of the bags will have between ___% and % green candies(Use ascending order. Round to one decimal place asneeded.)c) How would this model change if the bags contained even morecandies? (select the correct answer below)A. The center will be shifted up but the spread will be the same. B.The center will be shifted down but the spread will be the same. C.The center will be the same but there would be more spread. D.The center will be the same but there would be less spread.
