    Wolf, that’s precisely what I am uncertain about!

    Thanks to everyone who replied. The general consensus seemed to be that the book was wrong, so I didn’t worry about it on the regent. In the end, however, there weren’t any linear regression questions on the regent.

    R.L., the area of the parallelogram was 604 feet squared.

    I have another question, this time in US History. I guess my user name is no longer appropriate.

    Many opponents of the new deal programs claimed that these programs violated the American tradition of?

    (1) welfare capitalism

    (2) governmental regulations of business

    (3) collective bargaining

    (4) individual responsibility

    The correct answer is 4, verified a number of times. But why isn’t the answer 1? Can someone please explain to me the reasoning behind this answer?

    Thank you.

    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.
