Let p, and p, be the respective proportions of women with iron-deficiency anemia in each of two developing countries. A random sample of 1700 women from the first country yielded 549 women with iron-deficiency anemia, and an independently chosen, random sample of 1900 women from the second country yielded 576 women with iron-deficiency anemia. Can we conclude, at the 0.05 level of significance, that the proportion of women with anemia in the first country is greater 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 D formulas.) (a) State the null hypothesis Ho and the alternative hypothesis H. O P Ho : X S (b) Determine the type of test statistic to use. (Choose one) 0=0 050 020 (c) Find the value of the test statistic. (Round to three or more decimal places.) x 050 0>0 X ? (d) Find the p-value. (Round to three or more decimal places.) (e) Can we conclude that the proportion of women with anemia in the first country is greater than the proportion of women with anemia in the second country? Yes No
