A snack food manufacturer estimates that the variance of the number of grams of carbohydrates in servings of its tortilla chips is 1.26. A dietician is asked to test this claim and finds that a random sample of 24 servings has a variance of 1.13. At a = 0.01, is there enough evidence to reject the manufacturer's claim? Assume the population is normally distributed. Complete parts (a) through (e) below. Choose the correct statement below and fill in the corresponding answer boxes. O A. The rejection region is x2 > B. The rejection regions are x² < 9.26 and x2 > 44.18 Oc. The rejection region is x² < (c) Find the standardized test statistic x2. 20.63 (Round to two decimal places as needed.)
