You wish to estimate a population proportion with a confidence interval with a margin of error no larger than 0.03. You have a b

NikAS [45]

Answer:

The answer is 0.8788

Step-by-step explanation:

From question given, let us recall the following:

We know that Ƶα /2 * √p (1-p)/n

when we use n≤ 5000/10 =500

P = 0.75

The Margin of error = 0.03

Putting this values together we arrive at

Ƶα/2 = 0.03/√0.75 * 0.25/500

= 1.549

Now,

Ф (1.549) = 0.9394

Therefore the confidence level becomes:

1- (1-∝)/2 = 0.9394

∝ = 0.8788

The answer is 0.8788
