In that year, Ohio had 825 complaints of identity theft out of 3452 consumer complaints. Does this data provide enough evidence to show that Ohio had a higher proportion of identity theft than 22%? Test at the 1% level. State the hypotheses. Ho: p? v Ha: p|? v Calculate the test statistic. Round to four decimal places. Calculate the standardized test statistic. Round to three decimal places. Z = Find the p-value. Round to four decimal places. p-value State your decision. O Since the p-value is greater than .01, fail to reject Ho. O Since the p-value is less than .01, fail to reject Ho. O Since the p-value is less than .01, reject Họ. O Since the p-value is greater than .01, reject Ho. Interpret the results.

4.2.21 A team of researchers (Singer et al., 2000) used the Survey of Consumer Attitudes to investigate whether incen- tives would improve the response rates on telephone surveys. A national sample of 735 households was randomly selected, and all 735 of the households were sent an "advance letter" explaining that the household would be contacted shortly for a telephone survey. However, 368 households were randomly assigned to receive a monetary incentive along with the ad- vance letter, and the other 367 households were assigned to receive only the advance letter. Here are the data on how many households responded to the telephone survey. Received an incentive? Yes No Total Responded to the telephone survey? Yes 286 245 531 No 82 122 204 Total 368 367 735
