The margin of error for the interval (200 miles, 250 miles) is 25 miles.

What is an equation?

An equation is an expression that shows the relationship between two or more variables and number.

The confidence interval = mean (m) ± margin of error (e) = m ± e

Hence:

m + e = 250    (1)

m - e = 200    (2)

From the both equations:

m = 225, e = 25

The margin of error for the interval (200 miles, 250 miles) is 25 miles.
