The Weights Of A Certain Brand Of Candies Are Normally Distributed With A Mean Weight Of 0 8549 G And A Standard Deviati 1 (37.47 KiB) Viewed 38 times

The weights of a certain brand of candies are normally distributed with a mean weight of 0.8549 g and a standard deviation of 0.0525 g. A sample of these candies came from a package containing 459 candies, and the package label stated that the net weight is 391.9 g. (If every 0.8539 g for the net contents to weigh at least 391.9 g.) package has 459 candies, the mean weight of the candies must exceed 391.9 459 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 459 candies are randomly selected, find the probability that their mean weight is at least 0.8539 g. The probability that a sample of 459 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? Yes, because the probability of getting a sample mean of 0.8539 g or greater when 459 candies are selected is not exceptionally small.
