Compute the correlation coefficient for the data in Exercise 9.14. Is this correlation significant, and what does it mean to say that it is (or is not) significant?
Answer to relevant QuestionsInterpret the results from Exercises 9.11–9.13. Several times in this chapter I referred to the fact that a correlation based on a small sample might not be reliable. (a) What does “reliable” mean in this context? (b) Why might a correlation based on a small sample ...Use MYSTAT or another program to reproduce the results shown in Figure 9.11. Make up a set of five data points (pairs of scores) that have an intercept of 0 and a slope of 1. (There are several ways to solve this problem, so think about it a bit.) Using your own height and the appropriate regression equation from Exercise 10.19 or 10.20, predict your own weight. (If you are uncomfortable reporting your own weight, predict mine— I am 5980 and weigh 156 pounds—well, ...
