help pleaseeee

Create the data tables as I've demonstrated below (you can format however you want, you don't need to exactly copy) in a word processor. You should have 3 data tables - one for each country. Year United States Years since 1960 Economic Dependency Ratio (as a %) 7 For each country, use Excel to graph the EDR data and find the best fit regression model with the input being the number of years since 1960 and the output being the EDR. Each country can have a different type of model (such as quadratic, cubic, 4th degree, exponential, etc). Round all values to 2 decimal places, if necessary. Note: Don't exceed a 4th degree polynomial as it will make Part II more difficult. Explain how you know the model you chose is most accurate for each data set (re-watch my Accuracy of Models video if you need the review 18

this is the whole question. nothing else is missing
