A headline read, "More Than Half of Americans Say Federal Taxes Too High." The headline was based on a random sample of 1111 adult Americans in which 565 stated the amount of federal tax they have to pay is too high. Is this an accurate headline? Assume the x = 0.01 level of significance. Identify the null and alternative hypotheses for this test. OA. Ho: p0.50 H₁: p=0.50 OD. Ho:p>0.50 H₁: p=0.50 Find the test statistic for this hypothesis test. z=(Round to two decimal places as needed.) Determine the P-value for this hypothesis test. P-value = (Round to three decimal places as needed.) OB. Ho: p<0.50 H₁: p=0.50 E. Ho: p=0.50 H₁: p>0.50 OC. Ho: p=0.50 H₁: p<0.50 OF. Ho: p=0.50 H₁: p*0.50
