why not use 0.78*(1-0.78)to compute the variance? |

because we have the hypothesis MU=p,so Sigma=p(1-p). then take square root. |

terrible question. if you see data in red circles on the real exam, you're in the wrong test center. no explanation of what is going on plus it is completely foreign to the study notes for this los. |
