Transcribed Image Text:A snack food manufacturer estimates that the variance of the number of grams of carbohydrates in servings of its tortilla chips is 1.23. A dietician is asked to test this
claim and finds that a random sample of 16 servings has a variance of 1.16. 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.
H2: o21.23 (Claim)
Ha: o1.23
(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.
OA. The rejection region is x2
and x2>
O B. The rejection regions are x <
O C. The rejection region is x
