Let p, and P2 be the respective proportions of women with nutritional

Let p, and P2 be the respective proportions of women with nutritional anemia in each of two developing countries. If a random sample of 300 women from the first country yielded 75 women with nutritional anemia, and an independently chosen, randomn sample of 250 women from the second country yielded 77 women with nutritional anemia, find a 95% confidence interval forp,-p. Then complete the table below. P1 P2 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.) What is the lower limit of the 95% confidence interval? What is the upper limit of the 95% confidence interval? ?
