In one survey, 1247 out of 1521 randomly selected people said that typing on a cell phone while driving a car should be illegal. Consider a hypothesis test that uses a significance level of 0.03 to test the claim that over 80% of people believe that typing on a cell phone while driving a car should be illegal. a. What is the test statistic (insert letter: Z (standard normal), T (Student's t), F (Snedecor's F), X (chi-square))? b. What is the type of test (U = one-sided, B = two-sided)? c. What is the critical value, on the scale of the test statistic? (If the test is bilateral, answer only with the positive value).
