Assume that all grade-point averages are to be standardized on a scale between 0 and 6. Hov many grade-point averages must be obtained so that the sample mean is within 0.005 of the population mean? Assume that a 98% confidence level is desired. If using the range rule of range 6-0 thumb, o can be estimated as 4 = 1.5. Does the sample size seem practical? 4 ... The required sample size is (Round up to the nearest whole number as needed.) Does the sample size seem practical? O A. Yes, because the required sample size is a fairly small number. B. No, because the required sample size is a fairly small number. C. Yes, because the required sample size is a fairly large number. D. No, because the required sample size is a fairly large number.
