For developing countries in Africa and the Americas, letp1 and p2 be the respectiveproportions ofbabies with a low birth weight (below 2500 grams). A randomsampleof n1 = 2000 African women yielded y1 = 750with nutritional anemia anda random sample of n2 = 2000women from the Americas yielded y2 = 650 womenwithnutritional anemia. We shall test H0: p1 =p2 against the alternative hypothesisH1:p1 > p2 at α = 0.05.
1. What is the type of the test?
a) Right-tailed
b) Left-tailed
c) Two-tailed
2. Calculate Observed Test Statistic
3. Find the P-value of the test
4.Find the Critical Value of Critical Region of the Test
5. Draw Your Conclusion of the Test at α = 0.05
a) Fail to Reject H0
b) Reject H0
