Acme Toy Company prints baseball cards. The company claims that
30% of the cards are rookies, 60% veterans but not All-Stars, and
10% are veteran All-Stars. Suppose a random sample of 100
cards has 50 rookies, 45 veterans, and 5 All-Stars. Is this
consistent with Acme's claim? Use a 0.01 level of significance.
a) State the hypotheses and identify the claim with the correct
hypothesis.
1.
H0:percentages are the same (Not
claim)
H1: percentages are different(claim)
2.
H0:percentages are the
same (claim)
H1: percentages are different( Not
claim)
3.
H0:percentages are different
(claim)
H1: percentages are the same( Not
claim)
b) Find the critical value (s).
1. CV=9.210
2. CV=6.635
3. CV=11.345
c) Compute the test value:
1. Χ²= 19.58
2. Χ²=10.58
3. Χ²= 16.58
d) Make the decision.
1. Reject the null hypothesis.
2.Do not reject the null hypothesis.
e) Summarize the results.
1. There is enough evidence to support the claim.
2.There is not enough evidence to support the claim.
