Question: In a recent study the following percentages of U.S. car sales based on size were reported: 30.6% small, 45% midsize, 7.3% large, and 17.1%luxery. A recent survey of sales in a particular county indicated that of 100 cars sold 25 were small, 50 were midsized, 10 were large, and 15 were luxury. At the .05 level of significance can it be concluded that the proportions differ from those stated in the report?
