The equation for the line of best fit shows the relationship between the number of students enrolled
The equation for the line of best fit, then predict the number of students enrolled in 2011 is [tex]y = 90.2x - 177670.2[/tex]
How to determine the equation of the line of best fit
To do this, we make use of a graphing calculator that has the following calculation summary
- Sum of X = 10020
- Sum of Y = 15453
- Mean X = 2004
- Mean Y = 3090.6
- Sum of squares (SSX) = 10
- Sum of products (SP) = 902
- b = 90.2
- a = -177670.2
A regression equation is represented as:
[tex]y = bx + a[/tex]
So, we have:
[tex]y = 90.2x - 177670.2[/tex]
Hence, the regression equation is [tex]y = 90.2x - 177670.2[/tex]
