According to the distributor of a kind of trading card, 66% of the cards are common, 25% are uncommon, and 9% are rare. Pin-Yen wondered if the rarity levels of the cards she and her friends owned followed this distribution, so she took a random sample of 500 cards and recorded their rarity levels. Here are her results: Rarity level Common Uncommon Rare Cards 345 125 30 She wants to use these results to carry out a x? goodness-of-fit test to determine if the distribution of rarity levels of cards she and her friends owned disagrees with the claimed percentages. What are the values of the test statistic and P-value for Pin-Yen's test?
