Assume that all grade-point averages are to be standardized on a scale between 0 and 6. How many grade-point averages must be

Answer:

The sample size 'n' = 72,030

Step-by-step explanation:

Step(i):-

Given that the Estimate Error = 0.013

Given that the standard deviation of the Population = 1.5

The estimated error is determined by

$E = \frac{Z_{0.98} S.D }{\sqrt{n} }$

Step(ii):-

Given that the Level of significance = 0.98 or 0.02

Z₀.₀₂ = 2.326

The estimated error is determined by

$E = \frac{Z_{0.98} S.D }{\sqrt{n} }$

$0.013 = \frac{2.326 X 1.5 }{\sqrt{n} }$

$\sqrt{n} = \frac{3.489}{0.013} = 268.38$

Squaring on both sides, we get

n = 72,030

Final answer:-

The sample size 'n' = 72,030
