The null and alternate hypotheses are:

H₀:₁=₂

H₀:₁₂

A sample of 200 observations from the first population indicated thatx₁is 170. A sample of 150 observations from the second population revealedx₂to be 110. Use the 0.05 significance level to test the hypothesis.

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