Answer Section#

  • {‘value’: ‘Yes’, ‘feedback’: ‘Not quite. Assumptions required in part 3 include assuming that the education level of the husband and wife are independent and that the decision to get married is unrelated to education level. The husband/wife independence assumption is probably not reasonable, because people often marry another person with a comparable level of education. We will leave it to you to think about whether the second assumption is reasonable.’}

  • {‘value’: ‘No’, ‘feedback’: ‘Great! You got it.
