Given the sample data below, test the claim that the proportion of male voters who plan to vote Republican at the next presidential election is more than the percentage of female voters who plan to vote Republican. Use the P-value method of hypothesis testing and use a significance level of 0.10. Based on the result, can we say that Republicans resonate better with male voters than with female voters?

Men: n1 = 250, x1 = 146

Women: n2 = 202, x2 = 103

  1. State the requirement
  2. State the null and alternative hypotheses with the correct symbols
  3. Write all the statistics
  4. Write the formula of the test statistic and find the test statistic (you may use a calculator, but you are required to write down the command and all the numbers you enter)
  5. Find the critical value or the P-value (you may use a calculator, but you are required to write down the command and all the numbers you enter)
  6. Decide to reject or fail to reject H0 and explain the reason
  7. Wording the conclusion
