11
(Do not round until the final answer. Then round to the nearest thousandth as needed.)

Step 1 ：Given the data points, we have the following values: $x=[1,2,3,4,5,6,7,8,9,10]$ and $y=[0.1,0.7,1.1,2.1,2.9,3.1,3.1,4.4,4.6,5.1]$.

Step 2 ：The number of pairs of data, denoted as $n$, is 10.

Step 3 ：The sum of the x-values, denoted as $\sum x$, is 55.

Step 4 ：The sum of the y-values, denoted as $\sum y$, is approximately 27.2.

Step 5 ：The sum of the product of the x and y values, denoted as $\sum xy$, is 195.6.

Step 6 ：The sum of the squares of the x-values, denoted as $\sum x^2$, is 385.

Step 7 ：The sum of the squares of the y-values, denoted as $\sum y^2$, is approximately 100.28.

Step 8 ：Substitute these values into the formula for the correlation coefficient, $r=\frac{n(\sum xy)-(\sum x)(\sum y)}{\sqrt{[n\sum x^2-(\sum x{)}^2][n\sum y^2-(\sum y{)}^2]}}$.

Step 9 ：After calculating, we find that the correlation coefficient, $r$, is approximately 0.987611212433532.

Step 10 ：Rounding to the nearest thousandth, the final answer is $\boxed{{\displaystyle 0.988}}$.
