In testing the hypotheses:
H₀: p₁ - p₂ = 0
H₁: p₁ - p₂ > 0,
we find the following statistics:
n₁ = 200, x₁ = 80.
n₂ = 200, x₂ = 140.
a. What is the p-value of the test?
b. What is the conclusion if tested at a 5% significance level?
c. Estimate with 95% confidence the difference between the two population proportions.
