The accompanying table shows the average salary of baseball players starting in 1996. Using the data in the table, state the linear regression equation with the coefficients rounded to the nearest hundredth.
Number of Years Since 1990 Average Salary (thousands of dollars)
6 1263
7 1472
8 1516
9 1864
10 2067
11 2378
State the exponential regression equation with the coefficient and base rounded to the nearest hundredth.
Use your written regression equations, by how much does the exponential model exceed the average salary in 2010 predicted by the linear model, to the nearest thousand dollars?
I have typed the numbers into my calculator, and followed all the proper instructions for finding the linear regression equation, yet I am still getting the wrong answer. The answer should be y=204.61x+7.82, yet my answer is y=220.228x-111.942. As you can expect, my other answers are wrong too.
