The contingency table shows the results of a random sample of children with pain from musculoskeletal injuries treated with acetaminophen, ibuprofen, or codeine. At α = 0.10, can you conclude that the treatment is related to the result?

Perform the indicated chi-square independence test by doing the following.

(a) Identify the claim and state H₀ and H_a.

(b) Determine the degrees of freedom, find the critical value, and identify the rejection region.

(c) Find the chi-square test statistic. If convenient, use technology.

(d) Decide whether to reject or fail to reject the null hypothesis.

(e) Interpret the decision in the context of the original claim.
