Identify the correct option for claim. The correct option for claim is determined below as follows: From the information, given that at least 27% of the adults in a certain country think that their taxes will be audited. That is, At least 27% of adults in the country think that their taxes will be audited. Correct option: Option C State the hypotheses. That is, there is no evidence that the true proportion of the adults in the certain country think that their taxes will be audited is less than 0.27. That is, there is evidence that the true proportion of the adults in the certain country think that their taxes will be audited is less than 0.27.Obtain the value of the test statistic. The required value is, Thus, the value of the test statistic is –3.19.Obtain the P-value. Use Excel to obtain the probability value for z =–3.19 Follow the instruction to obtain the P-value: Open EXCEL Go to Formula bar. In formula bar enter the function as“=NORMSDIST” Enter the test statistic z as –3.19. Click enter EXCEL output: From the Excel output, the P-value is 0.0007. Thus, the P-value is 0.0007. Conclusion: The conclusion is obtained as shown below: Use the level of significance is 0.05. The p-value is less than level of significance. By rejection rule, reject the null hypothesis. That is, there is evidence that the true proportion of the adults in the certain country think that their taxes will be audited is less than 0.27.
