According to a report on consumer fraud and identity theft, 20% of all complaints for a year were for identity theft. In that year, Oregon had 714 complaints of identity theft out of 3449 consumer complaints. Does this data provide enough evidence to show that Oregon had a higher proportion of identity theft than 20%? Test at the 5% level. State the hypotheses. Họ: P?v Calculate the test statistic. Round to four decimal places. p= 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 less than .05, reject Ho. O Since the p-value is greater than .05, fail to reject Ho- O Since the p-value is greater than .05, reject Ho. O Since the p-value is less than .05, fail to reject H9. Interpret the results. O At the 5% level of significance, there is not enough evidence to show that the proportion of complaints due to identity theft in Oregon is less than 20%. O At the 5% level of significance, there is enough evidence to show that the proportion of complaints due to identíty theft in Oregon is more than 20%. O At the 5% level of significance, there is not enough evidence to show that the proportion of complaints due to identity theft in Oregon is not equal to 20%. O At the 5% level of significance, there is enough evidence to show that the proportion of complaints due to identity theft in Oregon is less than 20%. O At the 5% level of significance, there is not enough evidence to show that the proportion of complaints due to identity theft in Oregon is more than 20%. O At the 5% level of significance, there is enough evidence to show that the proportion of complaints due to identity theft in Oregon is not equal to 20%.
