Question

The table shows the population of Center City in various years. Use the data from 1990 and 2005 to create a linear model that predicts the population of the city (y) in a given year (x). In which year was the actual population of Center City most different from the value predicted by this model? Year City Population 1985 194,957 1990 197,800 1992 199,532 2000 203,750 2005 206,561 2012 210,600

Answer 1

The Table looks like something like this

Year      City Population

1985     194,957

1990     197,800

1992     199,532

2000     203,750

2005     206,561

2012     210,600

This  can be done by plotting these points on the line

After this Regression Analysis can be done in excel

y=(2767/5)x + 74709/5  

These are the points which are the outliers:

1990     197,800

2005     206,561
