Describe in your own words
the extent to which you do or don't find the first-order linear model a
reasonable representation of a sprinter's speed.
What is the significance
of the apparent change of parameters in the model over the time span from
1973 to 1993?
What is the significance
of the difference between parameter values for men and women?
Some track experts speculate
that men's and women's abilities in the sprints are becoming identical.
Do your conclusions support this? Why or why not? Do you have enough
evidence to determine whether there has been a change in relative abilities
since 1973? Explain.
