# State dmv records indicate that of all vehicles undergoing emissions testing during the previous year, 70% passed on the first try. a random sample of 200 cars tested in a particular county during the current year yields 124 that passed on the initial test. does this suggest that the true proportion for this county during the current year differs from the previous statewide proportion? test the relevant hypotheses using a 1⁄4 .05.
