The problem with this statement is that we are only presented with the “Given” which describes a linear correclation between number of cigarettes smoked and pulse rate. Linear correlation shows a relationship between the two variables – cigarettes and pulse rate- but never shows a causation. To show or prove a causation, a regression analysis needs to be performed.
Correlation is used to indicate relation, while a linear regression is a technique designed both to quantify a positive relationship between random variables, and prove that one variable is dependent on another variable
