a. Assume that nothing is known about the percentage to be estimated.
 
n=10681068
​(Round up to the nearest​ integer.)
b. Assume prior studies have shown that about

60​%

of​ full-time students earn​ bachelor’s degrees in four years or less.

n=10251025
​(Round up to the nearest​ integer.)
c. Does the added knowledge in part​ (b) have much of an effect on the sample​ size?
 
 

A.

​Yes, using the additional survey information from part​ (b) only slightly increases the sample size.
 

B.

​No, using the additional survey information from part​ (b) does not change the sample size.
 

C.

​Yes, using the additional survey information from part​ (b) dramatically reduces the sample size.
 

D.
