Solve the problem.A computer science major found that the grade he earned on his programs increased with the time he spent working on them in the computer lab. He made a table of the hours spent in the lab and the corresponding program grades. Let g represent the grade earned when h hours are spent in the lab.a)Draw a scatterplot for the data.b) Sketch a line that comes close to the data points in the scatterplot. Use your linear model to estimate the program grade when 3 hours are spent in the lab. State whether you used interpolation or extrapolation to obtain your result.
