Question

use the image to answer the question. number of states visited estimate the mean of the data in the dot plot. (1 point) the mean number of states visited is 5. the mean number of states visited is 4. the mean number of states visited is 6. the mean number of states visited is 2.

Explanation:

Step1: Count data - points

3 + 5+1 + 1+1 + 1+1 = 13

Step2: Calculate sum of values

(3×3)+(4×5)+(5×1)+(6×1)+(7×1)+(8×1)+(9×1)=9 + 20+5 + 6+7 + 8+9 = 64

Step3: Calculate mean

$\frac{64}{13}\approx 5$

Answer:

The mean number of states visited is 5.
