Question

Hi how are you , attached document not sure if my choice its correct

Answer 1

`\bar{x}=14.75`

1) To find the mean of this data set, we need to add them up and divide it by the number of data points.

2) So let's write them down:

12, 17,16,10,20,13,14,14,12,12,19,18

`\begin{gathered} \bar{x}=(12+17+16+10+20+13+14+14+12+12+19+18)/(12) \\ \bar{x}=14.75 \end{gathered}`

And that is the answer.
