![Assume that all grade-point averages are to be standardized on a scale between 0 and 6. How many grade-point averages must be obtained so that the sample mean is within 0.014 of the population mean? Assume that a 98% confidence level is desired. If using the range rule of thumb, σ can be estimated as
\[
\frac{{\text{{range}}}}{4} = \frac{{6-0}}{4} = 1.5
\]
Does the sample size seem practical?
The required sample size is [ ]
