Let p, and p, be the respective proportions of women with iron-deficiency anemia in each of two developing countries. A random sample of 2100 women from the first country yielded 336 women with iron-deficiency anemia, and an independently chosen, random sample of 1900 women from the second country yielded 365 women with iron-deficiency anemia. Can we conclude, at the 0.01 level of significance, that the proportion of women with anemia in the first country is less than the proportion of women with anemia in the second country? Perform a one-tailed test. Then complete the parts below. Carry your intermediate computations to three or more decimal places and round your answers as specified in the parts below. (If necessary, consult a list of formulas.)
