Question

find the mean, median, and mode of the data set round to the nearest tenth 15, 1 , 4, 4, 8, 7, 15, 4, 5

Answer 1

Mean = 7.5, median = 5, mode = 4

Explanation:

Answer 2

`15,\ 1,\ 4,\ 4,\ 8,\ 7,\ 15,\ 4,\ 15,\ 4,\ 5\to\underbrace{1,\ 4,\ 4,\ 4,\ 4,\ 5,\ 7,\ 8,\ 15,\ 15,\ 15}_(11)\\\\mean=(1+4+4+4+4+5+7+8+15+15+15)/(11)=(82)/(11)\approx7.5\\\\median:1,\ 4,\ 4,\ 4,\ 4,\ \boxed{5},\ 7,\ 8,\ 15,\ 15,\ 15\\\\mode:1,\ \underbrace{4,\ 4,\ 4,\ 4}_(4),\ 5,\ 7,\ 8,\ 15,\ 15,\ 15`

Answer: mean = 7.5, median = 5, mode = 4
