Assume that all grade-point averages are to be standardized on a scale between 0 and 6. how manygrade-point averages must be obtained so that the sample mean is within 0.006 of the population mean? assume that a 99% confidence level is desired. if using the range rule ofthumb, σ can be estimated as range/4=6-0/4 = 1.5. does the sample size seempractical?

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≥ where

Putting these numbers in the formula we get

N≥ =416025

yor answer is 7/6 times 5
