a. If 1 candy is randomly selected, find the probability that it weighs more than 0.8539 g. The probability is (Round to four decimal places as needed.) b. If 448 candies are randomly selected, find the probability that their mean weight is at least 0.8539 g. The probability that a sample of 448 candies will have a mean of 0.8539 g or greater is (Round to four decimal places as needed.) c. Given these results, does it seem that the candy company is providing consumers with the amount claimed on the label? because the probability of getting a sample mean of 0.8539 g or greater when 448 candies are selected exceptionally small.

Question

Please be sure answers are correct. 

The weights of a certain brand of candies are normally distributed with a mean weight of 0.8543 g and a standard deviation of 0.051 g. A sample of these candies
came from a package containing 448 candies, and the package label stated that the net weight is 382.5 g. (If every package has 448 candies, the mean weight of
382.5
- = 0.8539 g for the net contents to weigh at least 382.5 g.)
the candies must exceed
448
