Question

The following data represent the weights (in grams) of a random sample of 50 candies. The histogram is not bell-shaped so the empirical rule cannot be used. The histogram is bell-shaped so the empirical rule can be used. (c) Use the Empirical Rule to determine the percentage of candies with weights between 0.7 and 0.98 gram. (d) Determine the actual percentage of candies that weigh between 0.7 and 0.98 gram, inclusive. (e) Use the Empirical Rule to determine the percentage of candies with weights more than 0.91 gram. (f) Determine the actual percentage of candies that weigh more than 0.91 gram.

Explanation / Answer
