Answer:
2.462
Step-by-step explanation:
I added up the decimals.
2+0.4=2.4
2.4+0.06=2.46
2.46+0.002=2.462
And I got 2.462 as my final sum.
The coefficient of correlation is independent of change of scale and origin of the variable X and Y. Change of origin means some value has been added or subtracted in the observation. If we divide all observations with x then new mean =initial mean/x.
