A guidance counselor at a university is investigating demand for study abroad. The question before her is how engineering and humanities majors compare regarding interest in study abroad during summer. Random samples of 20 engineering and 20 humanities majors each were interviewed. Eight engineering majors and 12 humanities majors expressed interest in study abroad during the summer. Let p₁ be the proportion of engineering majors interested in study abroad and p2 be the proportion of humanities majors interested in study abroad. The estimated difference in the proportion of engineering and humanities majors p₁ - p2 has 95% confidence interval: (-0.472,0.109). (-0.504, 0.104). (-0.104, 0.504). (-0.109, 0.472).
