1.Find the sample size needed to estimate the percentage of voters in Florida who will vote Republican in the general election.Use a margin of error of three percentage points, and a confidence level of 99%.

a)Assume that and are unknown. P-hat & q-hat unknown. I think I did it right.

Za/2: (InvNorm: 0.005+ 0.99)= 2.576

n =(Za/2)^2 (pq)/E^2

= (2.576)^2 (0.5 * 0.5)/(0.3)^2

1843

b)Assume that based on prior studies, about 64% of Floridians vote Republican in the general election.
