Assume that all grade-point averages are to be standardized on a scale between 0 and 5. How many grade-point averages must be obtained so that the sample mean is within 0.006 of the population mean? Assume that a 95% confidence level is desired. If using the range rule of thumb, sigma can be estimated as StartFraction range Over 4 EndFraction equalsStartFraction 5 minus 0 Over 4 EndFraction equals1.25. Does the sample size seem practical?
