Question
Assume that all grade-point averages are to be standardized on a scale between 0 and 5. How many grade-point averages must be obtained so that the sample mean is within 0.007 of the population mean? Assume that a 99% confidence level
range 5-0
is desired. If using the range rule of thumb, o can be estimated as
=1.25. Does the sample size seem practical?
The required samplę 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. No, because the required sample size is a fairly large number.
O C. Yes, because the required sample size is a fairly large number.
O D. Yes, because the required sample size is a fairly small number.
