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 149 out of a random sample of 230 residents in the community said they recycle, is there enough evidence to support the policy maker's claim at the 0.10 level of significance?Perform a one-tailed test. Then complete the parts below. Carry your intermediate computations to three or more decimal places. a. State the null hypothesis H0 and the alternative hypothesis H1. b. Find the value of the test statistic. (Round to three or more decimal places.) c. Find the p-value. (Round to three or more decimal places.) d. Is there enough evidence to support the policy maker's claim that the proportion of residents who recycle is less than 70%?
