The proportion p of residents in a community who recycle has traditionally been 70%. A policymaker claims that the proportion is less than 70% now that one of the recycling centers has been relocated. If 158 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. (If necessary, consult a list of formulas.) (a) State the null hypothesis and the alternative hypothesis .

(b) Determine the type of test statistic to use. (Select one): Z, t, Chi-Square, or F

(c) Find the value of the test statistic. (Round to three or more decimal places.)

(d) Find the p-value. (Round to three or more decimal places.)

(e) Is there enough evidence to support the policy maker's claim that the proportion of residents who recycle is less than 70%? (Select one): Yes or No
