y rces A snack food manufacturer estimates that the variance of the number of grams of carbohydrates in servings of its tortilla chips is 1.25. A dietician is asked to test this claim and finds that a random sample of 16 servings has a variance of 1.11. At a= 0.10, is there enough evidence to reject the manufacturer's claim? Assume the population is normally distributed. Complete parts (a) through (e) below. A. Ho: 0² ?1.25 OB. Ho: ²1.25 H?:0² <1.25 Claim) Ha: 2 = 1.25 (Claim) OC. Ho: 021.25 (Claim) H?:0² #1.25 OD. Ho: 02 ?1.25 (Claim) H?:0² >1.25 (b) Find the critical value(s) and identify the rejection region(s). The critical value(s) is (are). (Round to two decimal places as needed. Use a comma to separate answers as needed.) Choose the correct statement below and fill in the corresponding answer boxes. y² and ² > OA. The rejection regions are y OB. The rejection region is x² < OC. The rejection region is ² >.
