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 is within 0.01 of the population mean? Assume that a 99% confidence level is desired. If using the range rule of thumb, o range 4-0 can be estimated as = -=1. 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? OA. No, because the required sample size is a fairly small number. OB. Yes, because the required sample size is a fairly large number. C. Yes, because the required sample size is a fairly small number. D. No, because the required sample size is a fairly large number. 4

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 is within 0.01 of the population mean? Assume that a 99% confidence level is desired. If using the range rule of thumb, o range 4-0 can be estimated as = 1. Does the sample size seem practical? 4 4 = The required sample size is (Round up to the nearest whole number as needed.) Does the sample size seem practical? A. No, because the required sample size is a fairly small number. B. Yes, because the required sample size is a fairly large number. OC. Yes, because the required sample size is a fairly small number. D. No, because the required sample size is a fairly large number.
