Question

According to a report by the U.S. Environmental Protection Agency (EPA), containers and packaging generated about 30.3% of all municipal solid waste (MSW) in the country in a recent year. This was the largest category of such waste. The next highest group was nondurable goods, which accounted for 21.3% of waste. This was followed by durable goods at 19.6%, yard trimmings/other at 14.9%,and food scraps at 13.9%.Suppose last year, one large mid-western U.S. city processed 300 (1,000 tons) of municipal solid waste (MSW) broken down by categories as follows:
Category ............ MSW (1,000 tons)
Containers and Packaging ... 86
Nondurable Goods ....... 74
Durable Goods ....... 70
Yard Trimmings/Other .... 41
Food Scraps ........ 29

Use the chi-square goodness-of-fit test to determine if there is a significant difference between the distribution of municipal solid waste in this mid-western city and the distribution released by the EPA. Let α = .10.
