At 95% confidence, how large a sample should be taken to obtain a margin of error of 0.05 for the estimation of a population proportion? Assume that past data are not available for developing a planning value for p*. (Round your answer up to the nearest whole number.)

The sample size 'n' = 384

Step-by-step explanation:

Step(i):-

Given data the margin of error = 0.05

The margin of error of the estimation of a population proportion is determined by

Step(ii):-

In data not given sample proportion 'p' but

we know that

cross multiplication, we get

0.05 ×√n = 0.98

squaring on both sides, we get

n = 384.16≅ 384

Final answer:-

The sample size 'n' = 384
