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 range 4-0 = = 1. is within 0.015 of the population mean? Assume that a 99% confidence level is desired. If using the range rule of thumb, a can be estimated as Does the sample size seem practical? 4 4 ... The required sample size is (Round up to the nearest whole number as needed.)
