Answer: The width of the confidence interval is 8%.
Step-by-step explanation:
- The width of the confidence interval is twice the margin of error.
Given : A 90 percent confidence interval to estimate a population proportion was calculated from a Sample proportion = 18 % .
Margin of error = 4 %.
Then , the width of the confidence interval = 2 x (Margin of error)
= 2 x (4%)
= 8%
Hence, the width of the confidence interval is 8%.
