Ms. Johnson's sixth grade class handed out surveys,
one to each student, about hair color and later posted the results:
75% of students had brown hair
20% of students had red hair
10% of students had blonde hair
What is the error in this sampling?
OA. Not that many students had brown hair.
O B. No one kept track of the number of surveys that went out.
O C.
The results add up to more than 100%
O D. Only two students were involved in tabulating the results.
