4. A researcher wants to test the claim that women who are exposed glycol ethers are more likely to have miscarriages than those who are not. Among the 40 women who are exposed glycol ethers that he randomly selected, 15 had miscarriages. Whereas, among the randomly selected 780 women who are not exposed glycol ethers, 130 had miscarriages. Is there enough evidence to conclude that the claim is correct? Use α = 0.01.
