Acme Toy Company prints baseball cards. The company claims that 30% of the cards are Rookies, 60% Veterans but not All-Stars, and 10% are Veteran All-Stars. Suppose a random sample of 100 cards has 50 Rookies, 45 Veterans, and 5 Veterans All-Stars. Suppose the random sample of 100 cards is said to have a standard deviation of 10.58 %, find a 90 % confidence interval for the population standard deviation.   Rookies Veterans Veterans All-Stars Observed 50 45 5 Expected 30 60 10
