A Government antipollution spokeperson asserts that more than 80% of the plants in the Glassboro area meet the antipollution standards.

She takes a random sample of published data on pollution emission for 64 plants in the area and finds that 56 plants meet the pollution standards. Do the sample data support the government claim at the 1% level of significance?
