Quadratic Regression Not all data will be If this is the case, you may choose a different regression model. Remember that looks like this: 4. The table below shows Alice's heart rate as it is measured every 5 minutes for 30 minutes while she exercises. Time (min) 140 15 Heart Rate (bpm) 34 142 152 a. Make a scatterplot of the data. b. Do you think this looks like a linear model? c. Find a quadratic regression model for the data. d. If the trend continues, predict her heart rate in 40 minutes. 5. The following data represents approximate heights for a ball thrown by a shot-putter as it travels x meters horizontally. Distance (m) Height (m) a. Find a linear and quadratic regression model. b. State which model best fits the data. c. Using that model, what would be the height of the ball if it travels 80 meters
