A snack food manufacturer estimates that the variance of the number of grams of carbohydrates in servings of its tortilla chips is 1.38. A dietician is asked to test this claim and finds that a random sample of 19 servings has a variance of 1.26. At a = 0 10, is ther enough evidence to reject the manufacturer's claim? Assume the population is normally distributed Complete parts (a) through (e) below (a) Write the claim mathematically and identify Ho and H OB.
