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 0.009 of the population​ mean? Assume that a 98​% confidence level is desired. If using the range rule of​ thumb, σ can be estimated as range4=6−04=1.5. Does the sample size seem​ practical?
