# 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 0.006 of the population​ mean? assume that a 99​% confidence level is desired. if using the range rule of​thumb, σ can be estimated as range/4=6-0/4 = 1.5. does the sample size seem​practical?
