Question
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 0.95. 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.
(a) Write the claim mathematically and identify H, and H.
DA. Ho:o#1.11
CB. H o =1.11 (Claim)
nts
H o=1.11 (Claim)
H, o +111
OD. Ho os1.11 (Claim)
H, o?>1.11
Ho o21.11
brary
H o<1.11 (Claim)
(b) Find the critical value(s) and identify the rejection region(s).
The critical value(s) is(are)
