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 0.007 of the range 4 - 0...

Does the sample size seem​ practical?

A. No, because the required sample size is a fairly large number.

B. Yes, because the required sample size is a fairly small number.

C. ​No, because the required sample size is a fairly small number.

D. Yes, because the required sample size is a fairly large number.

Extracted text: 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 0.007 of the range 4 - 0 population mean? Assume that a 99% confidence level is desired. If using the range rule of thumb, o 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.)
