Given that
The weight of 8 cats is 5, 13, 11, 13, 16, 13, 11, 7 and we need to find the mean of the data.
And the weight is in pounds.
Explanation -
The total number of cats is 8.
The formula for the mean is
[tex]Mean=\frac{Sum\text{ of all the observations}}{Toal\text{ observations}}[/tex]
Substituting the values we have
[tex]Mean=\frac{5+13+11+13+16+13+11+7}{8}=\frac{89}{8}=11.125[/tex]
After roundoff, the mean weight will be 11.1 pounds.
So the final answer is 11.1 pounds
