Question:

If confidence interval for population parameter µ is (180, 200), then margin of error is:

Options:

10

190

20

110

Correct Answer:

10

Explanation:

The correct answer is Option (1) → 10

$\text{Margin of error} = \frac{\text{Upper limit} - \text{Lower limit}}{2}$

$= \frac{200 - 180}{2} = \frac{20}{2} = 10$

$\text{Margin of error} = 10$
