The table to right gives the projections of the population of a country from 200

Question

The table to right gives the projections of the population of a country from 2000 to 2100. Answer parts (a) through (b). Find a linear function that models this data, with x equal to the number of years after 2000 and f(x) equal to the population in millions. f(x) = (Use integers or decimals for any numbers in the expression. Round to three decimal places as needed.) Only round the coefficients for entering your answer here, but do not round these coefficients in your calculator to find the answers for the following problems. Find the SSE and the average error of the model from (a). Note that the Average Error equals the square root of SSE divided by the number of data points. SSE = (Round to one decimal place as needed.) Average Error = (Round to one decimal place as needed.)

Explanation / Answer

f(x) = 241.6762 + 3.6763 * (x)

b)SSE =  2507.5 ;

Avg. rror = sqrt( sse / 6) = 20.44
