If you wanted to find the mean shoe size of students in an elementary school
which group would provide the most accurate sample?
O A. All the third-grade boys
B. An entire class of kindergarteners
O C. Two random students from each classroom in the school
D. All the fifth-grade girls
I think that its B because its an entire class meaning there are boys and girls and the average will be more accurate than the other answers because those have either only boys or girls not both.
