Carbohydrates in Candy The number of grams of carbohydrates contained in 1-ounce servings of randomly selected chocolate and nonchocolate candy is listed here. Is there sufficient evidence to conclude that there is a difference between the variation in carbohydrate content for chocolate and nonchocolate candy? Use α=0.05 and use σ1 for the standard deviation of the number of grams of carbohydrates in 1- ounce serving of chocolate.

Chocolate	29	25	17	31	41	28	32	29
Nonchocolate	39	29	29	41	30	38	41	10	37
