Acme Toy Company prints baseball cards. The company claims that 30% of the cards are rookies, 60% are veterans, and 10% are All-Stars. Suppose a random sample has the following cards. Test Acme's claim that 0.05 level of significance. the distribution is a good fit with the prints of baseball cards at an a Expected Frequency Observed Category Frequency Rookies 30 Veterans 105 All-Stars 15 a. Complete the table by calculating the expected frequencies. b. What is the chi-square test statistic? Round to three decimal places. c. What are the degrees of freedom? degrees of freedom = d. What is the p-value for this sample? Round to four decimal places. p-value = e. Is the p-value less than a? Yes v f. Make a decision. Reject the null. O Fail to reject the null. g. Make a conclusion. There is not sufficient evidence to support the claim that Acme's distribution of baseball cards is a good fit. O There is sufficient evidence to support the claim that Acme's distribution of baseball cards is a good fit.
