Answer:

Step-by-step explanation:

From the given information:

At 95% Confidence interval level,Level of significance $\alpha$ 0.05, the value of Z from the standard normal tables = 1.96

Margin of Error = 0.10

Let assume that the estimated proportion = 0.5

therefore; the sample size n can be determined by using the formula: $n =(\dfrac{Z}{E})^2 \times p\times (1-p)$

$n =(\dfrac{1.96}{0.1})^2 \times 0.5\times (1-0.5)$

$n =(19.6)^2 \times 0.5\times (0.5)$

n = 96.04

n $\approx$ 96
