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 = 1. Does range. 4-0 %3D is within 0.006 of the population mean? Assume that a 98% confidence level is desired. If using the range rule of thumb, o can be estimated as the sample size seem practical? The required sample size is (Round up to the nearest whole number as needed.) Does the sample size seem practical? O A. No, because the required sample size is a fairly small number. O B. Yes, because the required sample size is a fairly large number. O C. No, because the required sample size is a fairly large number. D. Yes, because the required sample size is a fairly small number.
