Question

use the confidence interval to find the margin of error and the sample mean. (1.65,1.99) the margin of error is. (round to two decimal places as needed.)

Explanation:

Step1: Recall the formula for margin of error

The margin of error \(E\) for a confidence interval \((a,b)\) is given by \(E=\frac{b - a}{2}\). Here \(a = 1.65\) and \(b=1.99\).

Step2: Calculate the margin of error

Substitute \(a = 1.65\) and \(b = 1.99\) into the formula \(E=\frac{b - a}{2}\).
