9. In Las Vegas there is a card game where people can bet on which suit of card a person draws (spades, diamonds, hearts, clubs.) (p1,p2,p3,p4)

You are testing the Nullhypothesis (H₀) that all suits appear with equal frequency.

You set the significance level at p =.05 .

You take a sample of size 500 and compute your test statistic to be Chi2= 8.52 ,with ap-value = 0.034

what conclusion would you reach?

A. RejectH₀and acceptH_a. Conclude that at least one ofp₁,p₂,p₃, andp₄exceeds 0.25.

At least one of the suits comes up more often than expected.

B. RejectH₀and acceptH_a. Conclude thatp₁,p₂,p₃, andp₄all exceed 0.25.

C. RejectH₀and acceptH_a. Conclude thatp₁,p₂,p₃, andp₄are all less than 0.25.

D. Do not rejectH₀. Conclude thatp₁=p₂=p₃=p₄= 0.25.

10. In a contingency table, when all the expected frequencies equal the observed frequencies, the calculated statistic equals zero.

A. True

B. False

11. When using the chi-square goodness of fit test, the smaller the value of the chi-square test statistic, the more likely we are to reject the null hypothesis.

A. True

B. False

12. The value of the chi-square test statistic can only be a positive number.

A. True

B. False

13. The p-value of the chi-square test statistic depends on the degrees of freedom.

A. True

B. False
