Textbook Question

Chapter 4, Problem 83CRE

Law School Selectivity and Employment The acceptance rate for a sample of law schools and the percentage of students employed at graduation are on this text’s website. A low acceptance rate means the law school is highly selective in admitting students. (Source: Internet Legal Research Group)

a. Do more selective law schools have better job-placement success? Make a graph that could addresses this question, report whether the trend is linear, and write a sentence answering the research question. If the trend is not linear, comment on what it shows and do not go on to part (b).

b. If the trend is linear, do the following:

I. Write the regression equation.

II. Interpret the slope of the regression equation.

III. Interpret the y-intercept of the regression equation or explain why it would be inappropriate to do so.

IV. Find and interpret the value of the coefficient of determination.

V. Use the regression equation to predict the percentage of students employed at graduation for a law school with a 50% acceptance rate.
