Step-by-step explanation:

The confidence interval is related to margin of error ; according to the relation :

Confidence interval = mean ± margin of error

Margin of Error = (upper boundary value – lower boundary value)

Confidence interval = 16.5% and 25.5%

Margin of Error = (25.5% – 16.5%)

Margin of Error = ±9
