Well what you would have to do is look for numbers that are easy to divide. For example, lets try 9000/10, and so the answer would be 900 and so if you divide the actually numbers, you could compare them, and see if 900 would be a reasonable.

Answer:

96

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
