The proportion p of residents in a community who recycle has traditionally been 70%. A policy maker claims
that the proportion is less than 70% now that one of the recycling centers has been relocated. If 150 out of
random sample of 230 residents in the community said they recycle, is there enough evidence to support th
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.)
