According to a report on consumer fraud and identity theft, 20% of all complaints for a year were for identitytheft. In that year, Pennsylvania had 748 complaints of identity theft out of 3493 consumer complaints. Doesthis data provide enough evidence to show that Pennsylvania had a higher proportion of identity theft than20% ? Test at the 5% level.State the hypotheses.Ho: P ?Ha: P ?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, fail to reject Ho.O Since the p-value is greaterreject Ho.O Since the p-value is greater than .05, fail to reject Ho.O Since the p-value is less than .05, reject Ho.Interpret the results.O At the 5% level of significance, there is enough evidence to show that the proportion of complaints dueto identity theft in Pennsylvania is more than 20%.O At the 5% level of significance, there is enough evidence to show that the proportion of complaints dueto identity theft in Pennsylvania is not equal to 20%.O At the 5% level of significance, there is enough evidence to show that the proportion of complaints dueto identity theft in Pennsylvania is less than 20%.O At the 5% level of significance, there is not enough evidence to show that the proportion of complaintsdue to identity theft in Pennsylvania is more than 20%.O At the 5% level of significance, there is not enough evidence to show that the proportion of complaintsdue to identity theft in Pennsylvania is less than 20%.O At the 5% level of significance, there is not enough evidence to show that the proportion of complaintsdue to identity theft in Pennsylvania is not equal to 20%.O

Let p be the population proportion of complaints for identity theft.Given that,Population proportion…
