A snack food manufacturer estimates that the variance of the number of grams of carbohydrates in servings of its tortilla chips is 1.11. A dietician is asked to test this claim and finds that a random sample of 22 servings has a variance of 1.23. At =0.01, is there enough evidence to reject themanufacturer's claim? Assume the population is normally distributed.

Write the claim mathematically and identify H0 and Ha.

(b) Find the criticalvalue(s) and identify the rejectionregion(s).

(c) Find the standardized test statistic 2.

(d) Decide whether to reject or fail to reject the nullhypothesis, and(e) interpret the decision in the context of the original claim.
