Answer:
96
Step-by-step explanation:
From the given information:
At 95% Confidence interval level,Level of significance 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 = 96.04
n 96
