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 the distribution is a good fit with the prints of baseball cards at an α=0.05 level of significance.

Category	Observed Frequency	Expected Frequency
Rookies	35
Veterans	100
All-Stars	15

Complete the table by calculating the expected frequencies.
What is the chi-square test statistic? Round to three decimal places.
