In random, independent samples of 400 adults and 275 teenagers who watched a certain television show, 224 adults and 121 teens indicated that they liked the show. Let p₁ be the proportion of all adults watching the show who liked it, and let p₂ be the proportion of all teens watching the show who liked it. Find a 95% confidence interval for p₁-P₂. Then find the lower limit and upper limit of the 95% confidence interval. Carry your intermediate computations to at least three decimal places. Round your responses to at least three decimal places. (If necessary, consult a list of formulas.) Lower limit: X Upper limit: 1
