You want to obtain a sample to estimate a population proportion. at this point in time, you have no reasonable estimate for the population proportion, so we assume p=.5. you would like to be 99% confident that you estimate is within 0.2% of the true population proportion. how large of a sample size is required?

416025

Step-by-step explanation:

For confidence interval of 99%, the range is (0.005, 0.995). Using a z-table, the z-score for 0.995 is 2.58.

Margin of error = 0.2% = 0.002.

Proportion is unknown. So, worse case proportion is 50%. p = 50% = 0.5.

\\

So, sample size required is 416025.

the answer to your question a or b but i am pretty sure it is b. i hope this : )

step-by-step explanation:

the answer is b.
