A headline read, "More Than Half of Americans Say Federal Taxes Too High." The headline was based on a random sample of 1241 adult Americans in which 640 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. A. Ho: p=0.50 OB. Ho: p=0.50 H₁: p>0.50 H₁: p<0.50 D. Ho:p>0.50 H₁: p=0.50 O E. Ho: p<0.50 H₁: p=0.50 Find the test statistic for this hypothesis test. z = 1.11 (Round to two decimal places as needed.) Determine the P-value for this hypothesis test. P-value = 0.134 (Round to three decimal places as needed.) State the conclusion for this hypothesis test. O C. Ho: p= 0.50 H₁: p0.50 OF. Ho:p #0.50 H₁: p=0.50 Reject Ho. There is not sufficient evidence at the α = 0.01 level of significance to conclude that of Americans say that federal taxes are too high.
