Results of a poll evaluating support for drilling for oil and natural gas off the coast of California. Suppose the number of college grads and non-college grads was fixed prior to the study. College Grad Not College Grad Support Oppose or Do not Know Total 164 132 236 268 400 400 (a) What percent of college graduates and what percent of the non-college graduates in this sample support drilling for oil and natural gas off the Coast of California? (b) Conduct a hypothesis test to determine if the data provide strong evidence that the proportion of college graduates who support off-shore drilling in California is different than that of non-college graduates. Be sure to clearly state the null and alternative hypotheses in symbols and in words, the test statistic you choose to use, it's distribution, the p-value, and your conclusions. (Use a = = 0.05)
