Assume that all gradepoint averages are to be standardized on a scale between D and 5. How many grade-mint averages must be obtained so that the sample mean is within 0.014 of the ran 5 0 population mean? Assume that a 95% condenoe level is desired. If using the range rule of thumb, a can be estimated as 499 = T =1.25. Does 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. Yes, because the requlred sample size is a fairly small number. 0 B. Yes, because the requlred sample size is a fairly large number. 0 c. No, because the required sample size is a fairly large number. 0 D. No, because the required sample size is a fairly small number
