Which of the following statements is/are true about scatter diagrams?
I. Knowledge about the relationship between the variables enables us to predict and control event.
II. The independent variable is the variable which is not affected by changes in the other.
III. The main purpose of a scatter diagram is to determine whether there is any pattern among the points.
The equation of the line of best fit for two variable X and Y, where X is the independent variable, is given by Y= 4.2X – 0.3, Predict the value of Y when X=7.1
