On the other hand, it might also be that by wild coincidence, the two names we draw for our sample just happen to be in the small group of ten grads who are now millionaires. In this case we will come to the incorrect conclusio ...

STAT 210: Final Exam: Name: 1. Answer the following True/False
... 11. Consider the following margin-of-error computations for each group. Margin of Error = 2 * Standard Error of Mean where standard error of mean = standard deviation / sqrt( sample size ) • Margin of Error for Private = 2 * 2.54 = 5.08 • Margin of Error for Public = 2 * 1.82 = 3.64 a. The margin-of ...
