When Brett Kavanaugh was nominated to be a Supreme Court justice, a survey of 1059 Americans showed that 50.6% of them disapproved of Kavanaugh. A newspaper published an article with thisheadline: "Majority of Americans Disapprove of Kavanaugh." Use a 0.10 significance level to test the claim made in that headline. Use the P-value method. Use the normal distribution as an approximationto the binomial distribution.Let p denote the population proportion of all Americans who disapproved of Kavanaugh. Identify the null and alternative hypotheses.Ho: PH₁: p▼(Type integers or decimals. Do not round.)Identify the test statistic.(Round to two decimal places as needed.)Identify the P-value.CP-value=(Round to three decimal places as needed.)State the conclusion about the null hypothesis, as well as the final conclusion that addresses the original claim.the null hypothesis. Theresufficient evidence tothe claim that a majority of Americans disapproved of Kavanaugh.
