What is the margin of error for a sample statistic for a population with a standard deviation of 7.75?

3241004551 [841]

Answer:

Margin of Error = 1.96 $\times$ 7.75 = 15.19

Step-by-step explanation:

i) Margin of Error of a population with a standard deviation of 7.75?

ii) Let us assume a two tailed test with a 95% confidence interval

iii) $Z_{\frac{\alpha }{2} } = Z_{\frac{\ 0.05 }{2} } = Z_{0.025} = 1.96$

iv) therefore Margin of Error = 1.96 $\times$ 7.75 = 15.19
