A random sample of 100 baseballs has been selected from each of two large crates of baseballs. One crate of baseballs was produced by Allen Sports Products; the other was produced by Baron Athletic Supply. Ten of the baseballs (10%) in the Allen sample and 18 of the baseballs (18%) in the Baron’s sample were determined to be too light to be used in Major League Baseball games. Use a chi square test to test the hypothesis that the proportion of baseballs that are too light is the same for both crates. Use a significance level of 5%.
