Answer 2

The value according to the Pearson Correlation is 3.06817837

Given:

x 55 56 58 59 60 60 62

y 35 38 37 39 44 43 44

To Find:

The coefficient of correlation of x 55 56 58 59 60 60 62 y 35 38 37 39 44 43 44

Solution:

The formula for Pearson's coefficient of correlation is,

 = $\frac{(x bar - x)(ybar- y)}{\sqrt{(x -xbar)^2}\sqrt{y-ybar} }$

=  $\frac{55(56)(58)(60)(60)(62)}{(35)(38)(37)(39)(44)(43)(44)}$

= 3.06817837

Hence, we get the value as  3.06817837 according to the pearson's correlation coefficient
