A study was conducted to determine the percent of children that want to grow up work in the same career as a parent. In a sample of 200 children, it was calculated that 43% wanted to eventually work in the same career as a parent. Construct the 95% confidence interval for the population proportion. Solution: phat = 0.43/200 = 0.00215 phat – qnorm(1.95/2)*sqrt(phat*(1-phat)/20 0) = -0.00426926 phat + qnorm(1.95/2)*sqrt(phat*(1-phat)/20 0) = 0.00856926 [-0.0043, 0.0086] What is wrong with this solution?
