0.673 or 0.67

Step-by-step explanation:

To calculate correlation coefficient of the data. We can use the following formula.

$r=\frac{\sum_{i}(x_i-\bar{x})(y_i-\bar{y})}{\sqrt{\sum_{i}(x_i-\bar{x})^2}\sqrt{\sum_{i}(y_i-\bar{y})^2} }$

Here 'x' represents the height and 'y' represents the weight.

Finding the individual values and putting them into the equation above we get,

r = 0.673

Therefore, the correlation coefficient of the given data is 0.673 or 0.67 (rounded to the nearest hundredth).
