question 74

Multiple Choice

• A) All \(\mu _ { A B } \neq 0\)
• B) \(\operatorname { All } \left( \mu _ { A B } - \mu _ { A } - \mu _ { B } + \mu _ { G } \right) = 0\)
• C) Not all \(\left( \mu _ { A B } - \mu _ { A } - \mu _ { B } + \mu _ { G } \right) = 0\)
• D) Not all \(\left( \mu _ { A B } + \mu _ { A } + \mu _ { B } - \mu _ { G } \right) = 0\)

Biased Estimator
