and, the impact of the number of years smoking a cigarette is directly on lung capacity, so it is Response variable.
we know that
<u>The correlation coefficient</u> is a number between
and
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 
therefore
<u>the answer is</u>
