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 0.008 of the population mean? Assume that a
range
4-0
99% confidence level 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.)
Does the sample size seem practical?
O A. No, because the required sample size is a fairly small number.
OB. Yes, because the required sample size is a fairly small number.
OC. Yes, because the required sample size is a fairly large number.
O D. No, because the required sample size is a fairly large number.
