At McMeck High School they decided to calculate the average GPA of all 950 students. The average GPA was 2.38 with a standard deviation of 0.59, what is the margin of error? Round

your answer to three decimal places.

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 = 0.037

Final -

The margin of error = 0.037

x is variable or an unknown value to find

example:

2x = 5 which means x = 3
