Question

Find the margin of error for the given values of c, s, and n.
c=0.95, s=2.5, n = 26

Answer 1

0.9609

Explanation:

Margin of error is expressed using the formula;

M = z * √s²/n

z is the 95% z score = 1.96

s is the standard deviation = 2.5

n is the sample size = 26

M = 1.96 * √2.5²/26

M = 1.96 * √0.2404

M = 1.96 * 0.49029

M = 0.9609

Hence the margin of error is 0.9609
