1. The explanatory in the given case is hours studied and response variable is GPA. Find and explain the correlation and coefficient of determination. Draw the scatter plot and Label it. Find the trend line. 2. Please find the residual plot and comment on the shape of the distribution. 3. There is one extreme suspected outlier in variable Hours studied. Exclude that data point from the data, and draw the scatter plot within part 1. Please find the trendline and comment on the difference between both trendlines.
