(Solution Library) For the following data, test the claim that p_1=p_2, at the 0.05 significance level. Low High n 1 = 5239 n 2 = 4939 x 1 = 52 x 2 = 25

Question: For the following data, test the claim that \({{p}_{1}}={{p}_{2}}\), at the 0.05 significance level.

Low High

n 1 = 5239 n 2 = 4939

x 1 = 52 x 2 = 25

  1. State the null and alternative hypotheses
  2. Calculate \({{\hat{p}}_{1}}\) and \({{\hat{p}}_{2}}\)
  3. Find the pooled estimate \(\bar{p}\)
  4. Find the z-statistics
  5. Find the critical z-value
  6. Find the p-value
  7. State the conclusion
  8. Construct a 90% confidence interval estimate for the difference between the two proportions
  9. Does the confidence interval estimate agree with your conclusion? Explain why?
  10. Does the confidence interval estimate always result in the same conclusion as the hypothesis test? Explain why or why not.
