Question: In each case, determine whether the sample sizes are large enough to conclude that the sampling distribution \({{p}_{1}}-{{p}_{2}}\) is approximately normal.

1. n ₁ = 12, n ₂ = 14, \({{\hat{p}}_{1}}\) = .42, \({{\hat{p}}_{2}}\) = .57
2. n ₁ = 12, n ₂ = 14, \({{\hat{p}}_{1}}\) = .92, \({{\hat{p}}_{2}}\) = .86
3. n ₁ = n ₂ = 30, \({{\hat{p}}_{1}}\) = .70, \({{\hat{p}}_{2}}\) = .73
4. n ₁ = 100, n ₂ = 250, \({{\hat{p}}_{1}}\) = .93, \({{\hat{p}}_{2}}\) = .97
5. n ₁ = 125, n ₂ = 200, \({{\hat{p}}_{1}}\) = .08, \({{\hat{p}}_{2}}\) = .12
