Question

The Town of Normal offers a curbside recycling to residents in single family and duplex homes. Curbside recycling is collected weekly on a regular trash collection day. Twenty-one residents from a sample of 30 indicated that they favored curbside recycling in their city. The city council is interested in finding out whether or not there is a significant difference in the favoring and not favoring curbside recycling in their community. Use the normal approximation to the Binomial, and conduct a two-tailed test at the 0.10 significance level. Suppose that favoring curbside recycling was given a "+" sign and not-favoring curbside recycling a "-" sign. Conduct a hypothesis test.
