  1. Suppose that national data indicate that 55% of Americans drive to work, 25% take public transportation, 12% bike, and 8% walk. A random sample from one particular city yielded 36 respondents who drove to work, 11 who took public transportation, 18 who biked, and 9 who walked. Conduct an appropriate hypothesis test of the claim that this city’s commuting habits are consistent with the national distribution. [Be sure to state the hypotheses, find the test statistic, find the p-value or critical value (either is OK), and draw the appropriate conclusion about the claim.]
