Do Cricketers Tend to Have Longer Careers Than Tennis Players? The figure shows mean length of career versus playing age expectancy (in years) for cricketers and tennis players, until the age of 50.

Cricketers are represented by blue diamonds, and tennis players are represented by red squares.

a. Find your own age on the graph and estimate your playing age expectancy as a cricketer and tennis player.

b. Would it make sense to find the best straight line for this graph? Why or why not?

c. Is it reasonable to predict the length of career for a person who is 55 from the regression line for these data? Why or why not?

d. Explain what it means that nearly all of the blue diamonds (for cricketers) are above the red squares (for tennis players).

(Above the age of 35, the red squares cover the blue diamonds because both are in the same place).
