The proportion

p

of residents in a community who recycle has traditionally been

60%

. A policy maker claims that the proportion is less than

60%

now that one of the recycling centers has been relocated. If

128

out of a random sample of

240

residents in the community said they recycle, is there enough evidence to support the policy maker's claim at the

0.01

level of significance?

Perform a one-tailed test. Then complete the parts below.

Carry your intermediate computations to three or more decimal places. (If necessary, consult a list of formulas.)
