SOLVED: Assume that all grade-point averages are to be standardized ona scale between 0 and 4. How many grade-point averages must beobtained so that the sample mean is within 0.014 of the populationmean? Assume that a 99% confidence level is desired. If using therange rule of thumb, σ can be estimated as range 4= 4−0 4=1. Doesthe sample size seem practical?
