Question

Here is the histogram of a data distribution. All class widths are 1. Which of the following numbers is closest to the mean of this distribution?A.2B.3C.10D.5E.4

Answer 1

we have that

mean=(2x1+3x4+4x5+5x4+6x2+7+8+9+10)/20

mean=(2+12+20+20+12+7+8+9+10)/20

mean=100/20

mean=5

therefore

The answer is option D
