Answer:

So, the population mean is 3.66.

Step-by-step explanation:

We will calculate the average value by summing all the values and dividing by the  size of sample.

We have population contains six members, with values 1,1,2,3,5,10.

Therefore, n=6.  

We use the formula to calculate the population mean:

[tex]\mu=\frac{x_1+...+x_n}{n}\\\\\mu=\frac{1+1+2+3+5+10}{6}\\\\\mu=\frac{22}{6}\\\\\mu=3.66[/tex]

So, the population mean is 3.66.
