You are given the task to determine the relationship between student's study hour and their grades achieved. In your presentation, you must answer those question; (a) Sketch a scatter plot for a data. (b) Find the equation of the least squares line that will enable us to predict a student's grade based on his or her study hour. Interpret the result. (c) Calculate the coefficient of determination and coefficient of correlation.
