A polling company conducts polls using both mailed questionnaires and telephone calls. For one particular poll, the company sent out 1,000 questionnaires and attempted to call 1,000 different households. Of those, 313 of the questionnaires were sent back, and 291 of the calls resulted in a completed interview. Perform a two-proportion hypothesis test to determine whether the response rates between questionnaires and phone calls are different. Assume that the samples are random and independent. Use a = 0.05. Let the questionnaires correspond to the first sample and the calls correspond to the second sample. (a) H. Pi = P2: H.: Pipz, which is a two-tailed test. (b) Use a TI-83, TI-83 Plus, or TI-84 calculator to test if the proportions are different. Identify the test statistic, z, and p-value from the calculator output. Round the test statistic to two decimal places and the p-value to three decimal places. Provide your answer below: test statistic p-value =
