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
