Sketch a scatterplot data
Let s represent salary and let t represent year. The least squares regression
line that best fits this sata set is s = 13.199t- 25,812. Sketch this line on
the graph with the scatterplot and describe what you see.
Compare this line with the line given in Example 6.2. What value for
salary do you get from each of the lines if you substitute the value 2001
for the variable t, and what do those values tell you?
Please find the solution/explanation attached herewith.
The following table gives the median weekly earnings of full-time wage and salary workers 25 years and older who have had one to three years of college.
