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 0.011 of the populationmean? assume that a 99% confidence level is desired. if using the range rule of thumb, σ can be estimated as range/4 = 4-0/4 = 1. (a) what is the required sample size? (b) does the sample size seem practical? explain why.
