Question

(1 point) Recent polls indicate that if a federal election would be held today, 32% of Canadian voters would cast his/her vote for the Liberal Party candidate in his/her riding. Suppose you are a political pollster, and you are to randomly pick $n = 309$ Canadian voters, asking each Which political party will you support in the next federal election? (a) What can you expect the value of $hat{p}$ to be? (use at least two decimals in your answer) (b) Find the value of the standard deviation of $hat{p}$. Enter your answer using at least three decimals. $sigma_{hat{p}} = $ (c) Find the probability that proportion of your sample of 309 that will indicate support for the Liberal Party is at least 30% to at most 34%. Use at least four decimals in your answer. $P(0.3 le hat{p} le 0.34) = $ (d) 5% of the time, the observed value of your statistic $hat{p}$ will exceed what value? Use at least four decimals in your answer. (use four decimals in your answer)
