BSC Finding the Best Model. ?Construct a scatterplot and identify the mathematical model that best fits the given data. Assume that the model is to be used only for the scope of the given data, and consider only linear, quadratic, logarithmic, exponential, and power models. Deaths from Motor Vehicle Crashes?Listed below are the numbers of deaths in the United States resulting from motor vehicle crashes. Use the best model to find the projected number of such deaths for the year 2020.
Solution 10 BSC Step 1 : Given, The number of deaths in the united states resulting from motor vehicle crashes. By using Minitab > Choose Stat regression Fitted line plot > We can choose linear, quadratic and logarithmic in fitted line plot. > Choose quadratic ok on the graph option Step 2 : The quadratic model is D = -50597784 + 51141*y - 12.91*y 2 Here, D is the dependent variable which indicates the number of deaths and Y is the independent variable which indicates the year. The quadratic model model fits the data better R-squared value 65.2%. We can say that 65.2% of variation in deaths due to motor crashes .
