1-2. Linear Regression problem.

(1) since the x data "jumps" in steps of 10, I've filled in the x data, fill in x^, y, y^ next

(2) Using 2-variable stat, find:

(3) working in adjusted units, the slope of the best fit line = (c)/(a), the y-intercept = 0

(4) fill in the last 3 columns of the table

(5) Compute D directly.

(6) computer using the formula

(7) D = (1-r²)

(8) using linear regression on your calculator, find the slope of the best fit line and r

(9) plot the data and regression line on the graph
