Assume that all grade-point averages are to be standardized on a scale between 0 and 4. How many grade-point averages must be obtained so that the sample mean is within 0.01 of the population mean? Assume that a 95% confidence level is de-sired. Assume we estimate o to be range/4. If conducting a telephone survey, does the sample size seem practical?
