A sample of 14 small bags of the same brand of candies was selected. Assume that the population distribution of bag weights is normal. The weight of each bag was then recorded. The mean weight was 3 ounces with a standard deviation of 0.15 ounces. The population standard deviation is known to be 0.1 ounce. NOTE: If you are using a Student's t-distribution, you may assume that the underlying population is normally distributed. (In general, you must first prove that...

The weights of a certain brand of candies are normally distributed with a mean weight of 0.8614 g and a standard deviation of 0.0511 g. A sample of these candies came from a package containing 447 candies, and the package label stated that the net weight is 381.4 g. (lf every package has 447 candies, the mean weight of the candies must exceed 381.4 0.8532 g for the net contents to weigh at least 381.4 g.) 447 a. If 1...
