Question

A student surveys 35 students at her school to see how many different states that have visited. The results are shown in the dot plot.

I think it's 4 but I'm not sure.

Answer 1

The mean is the average. You need to add all the numbers together then divide by the number of students.

1 +1 +2+2+2+3+3+3+3+3+4+4+4+4+4+4+4+5+5+5+5+5+6+6+6+6+7+7+7+8+8+8+9+10+11 = 175

175 / 35 = 5

The answer is C) 5
