Answered by maham237 @ 02/12/2020

we know that

The correlation coefficient is a number between $-1$ and $+1$ that represent the linear dependence of two variables or sets of data

Using the function CORREL in a excel tool, calculate the correlation coefficient (r)

see the attached table

the correlation coefficient for the data in the table is equal to $1$

therefore

the answer is

$r=1$
