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 0.013 of the population mean? Assume that a 98% confidence level is desired. If using the range rule of thumb, σ can be estimated as range/4=(6-0)/2=1.5. Does the sample size seem practical?
