Calculate the mean, median, and standard deviation for the total number of candies (per bag). Construct a histogram of the total number of candies (per bag). Use the z-score method to identify any potential outliers and outliers. Assume the total number of candies is normally distributed, calculate the probability that a randomly sampled bag has at least 55 candies in a bag. If a random sample of 50 bags is selected, find the probability that the mean number of candies...
