An poll is conducted in which 2500 people who just voted are randomly selected.1300 say they voted for David.?
There are only 2 candidates in this election.
a) Calc the usual point estimate of the true proportion of individuals voting for David, p-hat. is it biased or unbiased?
b) what is the variance of the estimator used in part a?
c) how would u change the sample size if u wished to make the variance 1/4th as large as the value calculated in part b?|||73.4% of the time statistics are 59.2% wrong anyway, so don't worry about it :)
