Answer: 13.1

Step-by-step explanation:

The data set we have is:


\left\{ 7.39,8.69,9.28,9.66,10.20,10.84,12.15,36.44\right\}

To calculate the mean, we need to add all the quantities and divide by the number of elements in the data set:


Mean=\frac{sum\text{ of all the data}}{number\text{ of elements}}

The number of elements in the data set is: 8 elements

And the sum of all the data is:


7.39+8.69+9.28+9.66+10.20+10.84+12.15+36.44=104.65

So, we substitute this into the Mean formula, and get the following result:


\begin{gathered} Mean=(104.65)/(8) \\ Mean=13.081 \end{gathered}

Rounding to the nearest tenth (1 decimal place):


Mean=13.1
