Manufacturing companies strive to maintain production consistency, but it is often difcult for outsiders to tell whether they have succeeded. MaM's 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 260 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 of green candies they might expect in the 260-candy bag. It's appropriate to use a Normal model because np = 26' and nq = 234 , which are both greater than or equal to 10. The samples in each bag should be random and independent. (Type integers or decimals. Do not round.) b) Use the 68-95-997lr Rule to describe how this proportion might vary from bag to bag. About 68% of the bags will have between \"/0 and % green candies. (Use ascending order. Round to one decimal place as needed.)
