Answer:
The correlation coefficient is 0.981
Step-by-step explanation:
Given the data of height and weight, we have to find the correlation coefficient
The formula of correlation coefficient is
[tex]r = \frac{n\sum_ . xy - (\sum_. x)(\sum_. y)}{\sqrt}n\sum_. x^{2} - (\sum_. x)^{2} {\sqrt}n\sum_. y^{2} - (\sum_. y)^{2}[/tex]
⇒ [tex]r =\frac{8(130753) - (583)(1784)}{\sqrt}8(42611) -(583)^{2} {\sqrt}8(402436) - (1784)^{2}[/tex]
⇒ r = 0.981
Hence correlation coefficient will be 0.981
