The margin of error is \square (Round to three decimal places as needed.)

Studdy Solution
Calculate the margin of error using the formula:
E=t×sn E = t^* \times \frac{s}{\sqrt{n}}
Substitute the known values:
E=2.819×623 E = 2.819 \times \frac{6}{\sqrt{23}}
Calculate:
E2.819×64.796 E \approx 2.819 \times \frac{6}{4.796}
E2.819×1.251 E \approx 2.819 \times 1.251
E3.525 E \approx 3.525
Round to three decimal places:
E3.525 E \approx 3.525
The margin of error is:
3.525 \boxed{3.525}
