The table shows the total number of trade apprenticeships Canada each year from 1991 to 1997 a) Consider the year 1991 as year #0. Create a scatter plot of the data on the next page using the DESMOS graphing calculator. apprenticeships 192,945 Year 1991 1992 180,965 1993 168,985 1994 163,750 1995 163,370 165,325 171,180 1996 1997 b) From the scatter plot, which model appears most appropriate: linear, quadratic, exponential. Give reason for your answer c) Generate a model for the data (line/curve of best fit) using regression. Write the equation of the model that best fits the data.

Question
The table shows the total number of trade apprenticeships in Canada each year from 1991 to 1997 a) Consider the year 1991 as year #0. Create a scatter plot of the data on the next page using the DESMOS graphing calculator. apprenticeships 192,945 Year 1991 1992 180,965 168,985 163,750 163,370 1993 1994 1995 1996 165,325 171,180 1997 b) From the scatter plot, which model appears most appropriate: linear, quadratic, exponential. Give reason for your answer c) Generate a model for the data (line/curve of best fit) using regression. Write the equation of the model that best fits the data. d) Use the model to predict when apprenticeships will return to 1991 levels.
