Answer:
a. 1844
b. 664
Step-by-step explanation:
a. No estimate of proportion is given so we will assume:
{p} = {q} = 0.5
For 99% confidence, z = 2.576
E = 0.03
Hence, Required sample size n = (0.5)*(0.5)*(2.576/0.03)^2 = 1844
b. {p} = 0.10
{q} = 1 - {p}
{q} = 1 - 0.10
{q} = 0.90
For 99% confidence, z = 2.576
E = 0.03
Hence, Required sample size n = (0.1)*(0.9)*(2.576/0.03)^2 = 664
c. There would have been no effect on parts a and b if entire US has been chosen because minimum sample size required is not dependent on population size.
The answer is 129. California and Florida have a combined total of 125 counties. If you are trying to figure out how many more Texas has than the combined total of Florida and California, you would do 254-125, which equals your answer of 129.
