Answer 1

Answer:

The margin of error = 0.037

Step-by-step explanation:

Explanation:-

Given that the mean of the Population(μ) = 2.38

Given that the standard deviation of the Population(σ) = 0.59

Given sample size 'n' = 950

Level of significance = 0.05

The critical value( Z₀.₀₅) = 1 .96

The margin of error is determined by            

                       $M.E = \frac{Z_{\alpha } S.D}{\sqrt{n} }$

                      $M.E = \frac{1.96 (0.59)}{\sqrt{950} }$

                      M.E = 0.037

Final answer:-

The margin of error = 0.037
