2) A regression in statistics is statistical analysis that assess the relationship between two variables. The calculation is used to determine the relationship between two variables. You are given the task to determine the relationship between student's study hour and their grades achieved. You must answer these questions: I. Sketch a scatter plot for a data. II. 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. III. Calculate the coefficient of determination and coefficient of correlation.
