Answer:
0.673 or 0.67
Step-by-step explanation:
To calculate correlation coefficient of the data. We can use the following formula.
[tex]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} }[/tex]
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).
