[solved]-The Total Human Population Listed For 1980 1990 2000 2010 Is Listed Below Predic

The total human population listed for 1980, 1990, 2000, 2010 is listed below  

Predict the population for 2020 and tell me how you arrived at the value; 1-2 sentences. If I can’t read your process, it won’t count 

 here is a hint; a fair amount of you already latched on to scatter plots  Use years as X, it’s ok to convert them to 1,2,3,4  Put the population in as just the coefficient( 4.45  5.28, etc )

THEN ( here’s the cool part ) Right click on any one of the data points. A menu appears  SELECT 3 items from the list:  LINEAR  Display RSquared on chart  Display Regression Equation on chart 

That regression equation is a forecast tool and let X = the year 2020.  if you used integers for X, make it the correct integer data based on the years provided 

year    population

1980    4.45 x 109

1990    5.28 x 109

2000    6.08 x 109

2010    6.85 x 109
