Question
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 population​ mean? Assume that a
95​%
confidence level is desired. If using the range rule of​ thumb,
σ
can be estimated as
range4=4−04=1.
Does the sample size seem​ practical?
