The null and alternate hypotheses are:

H0: π1 = π2
H0: π1 ≠ π2

A sample of 200 observations from the first population indicated that x1 is 170. A sample of 150 observations from the second population revealed x2 to be 110. Use the 0.05 significance level to test the hypothesis.

  1. State the decision rule. (Negative values should be indicated by a minus sign. Round your answers to 2 decimal places.)

  1. Compute the pooled proportion. (Do not round the intermediate values. Round your answer to 2 decimal places.)

  1. Compute the value of the test statistic. (Do not round the intermediate values. Round your answer to 2 decimal places.)

  1. What is your decision regarding the null hypothesis?

  • Reject

  • Do not reject
