State DMV records indicate that of all vehicles undergoing emissions testing during the previous year, 70% passed on the first try. A random sam- ple 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 propor- tion for this county during the current year differs from the previous statewide proportion? Test the relevant hypotheses using a 1⁄4 .05.
