Answer:

416025 grade-point averages must be obtained so that the sample mean is within 0.006 of the population mean. But this size too big and is not practical.

Step-by-step explanation:

Minimum required grade-point averages can be found using the formula

N≥[tex](\frac{z*s}{ME} )^2[/tex] where

N is the sample size
z is the corresponding z-score in 99% confidence level (2.58)
s is the standard deviation (1.5)
ME is the margin of error (0.006)

Putting these numbers in the formula we get

N≥[tex](\frac{2.58*1.5}{0.006} )^2[/tex] =416025
