Assume that all grade-point averages are to be standardized on a scale between 0 and 5. how many grade-point averages must be obtained so that the sample mean is within 0.007 of the population mean? assume that a 95% confidence level is desired. if using the range rule of thumb, sigma can be estimated as startfraction range over 4 endfraction equalsstartfraction 5 minus 0 over 4 endfraction equals1.25. does the sample size seem practical? explain why?
