i tried that and got roughly the same answer using the p-hat formula. (n is 641, not 0.462 ).

i had a question about that too though. terzi, would that be applicable to case 1 question 1? with N-207,700,000 (total population of statscan)

also, for case 1 question2. is N limited to people that make 75+k (when using p=68/177)
