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 0.01 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=5−04=1.25.

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
0.01
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=5−04=1.25.
Does the sample size seem​ practical?
 
 
 
The required sample size is

​(Round up to the nearest whole number as​ needed.)
Does the sample size seem​ practical?
 
 
A.
​Yes, 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 large number.
 
D.
​No, because the required sample size is a fairly small number.
