Question

Find the margin of error for the given values of c, o, and n. C =0,95, 0 =2.6, n = 100

Answer 1

Answer:

Margin of error = 0.475

Step-by-step explanation:

Given that,

Confidence level, C = 0.95

Sample size, n = 100

Population standard deviation, $\sigma = 2.6$

When the confidence level is 0.95, the value of $z_{\alpha/2}=1.645$

The margin of error is given by :

$E=z_{\alpha/2}\times \dfrac{{\sigma}}{\sqrt{n} }\\\\E=1.645\times \dfrac{{2.6}}{\sqrt{81} }\\\\=0.475$

So, the margin of error is 0.475.
