Refer to Example 11 and Exercise 13.40, with = predicted winning high jump and x1 = number
Question:
a. In allowing the lines to have different slopes, the overall model allows for ____________________ between gender and year in their effects on the winning high jump. (Fill in the correct word.)
b. Show that both equations yield the same predicted winning high jump when x1 = 380 (that is, 380 years after 1928, or in 2308).
c. Is it sensible to use this model to predict that in the year 2308 men and women will have about the same winning high jump? Why or why not?
