A survey of 1,002 was taken, and 580 responded that they used public transportation. a. State the null hypothesis and the alternate hypothesis. Round the final answers to 2 decimal places. H0: p = H1: p ≠ b. State the decision rule for 0.05 significance level. (Negative answer should be indicated by a minus sign. Round the final answers to 2 decimal places.) Reject H0 if z > or z < . c. Compute the value of the test statistic. (Negative answer should be indicated by a minus sign. Round the final answer to 2 decimal places.) Value of the test statistic d. At the 0.05 significance level, is it reasonable to conclude that the survey results indicate a change? H0. There is evidence to indicate that the results have changed.
