Olympic heptathlon

Heptathlon 2004 again. We saw the data for the women’s 2004 Olympic heptathlon in Exercise 51. Are the two jumping events associated? Perform a regression of the long-jump results on the high-jump results.

a) What is the regression equation? What does the slope mean?

b) What percentage of the variability in long jumps can be accounted for by high-jump performances?

c) Do good high jumpers tend to be good long jumpers?

d) What does the residuals plot reveal about the model?

e) Do you think this is a useful model? Would you use it to predict long-jump performance? (Compare the residual standard deviation to the standard deviation of the long jumps.)
