Nadya [2.5K]

Answer: The sample size would be needed = 385

Step-by-step explanation:

Let p be the prior population proportion.

Margin of error = E

When not estimate of p is given , the formula to calculate the minimum sample size n = $0.25(\dfrac{z^*}{E})^2$ , where z* = critical value for given confidence interval.

Here z* for 95% confidence level is 1.96.

E=5%=0.05

Then $n=0.25(\dfrac{1.96}{0.05})^2\approx385$

Hence, the sample size would be needed = 385
