A glоw stick lоses its аbility tо emit light stаrting аt the moment it is first broken. The following table illustrates the amount of light emitted by a standard glow stick. Use the table to answer the questions below. Time (h) Light (lumens) 0 0.860 1 0.695 2 0.562 3 0.455 4 0.367 5 0.305 6 0.247 a) Create a scatterplot for the data. Insert your work as an image. (1 marks) b) Determine the equation of the parabola of best fit and coefficient of determination by performing a quadratic regression (2) c) Perform an exponential regression to determine the resulting equation and coefficient of determination. (2) d) Which model is a better fit for the data up to 6 hours? Explain. (2) e) Argue which model you would use if you only needed to extrapolate beyond 6 hours. Explain. (3)
