Q. 4In regression analysis, the so-called regression line summarizes the stochastic relationship between dependent variable y and independent x, while also minimizing the errors made when the equation of that line is employed to estimate y from x.

Q. 5A stochastic relationship is a relationship between any two variables, Y and X, such that many possible values of Y can be associated with any one value of X.
Indicate whether the statement is true or false
Q. 6A direct relationship is a relationship between any two variables, Y and X, such that the value of Y is uniquely determined whenever the value of X is specified (only Y exists for each X).
Indicate whether the statement is true or false
Q. 7In regression analysis, the dependent variable is a variable whose value is unknown and is being explained or predicted with the help of another variable.
