The accompanying technology output was obtained by using the paired data consisting of foot lengths (cm) and heights (cm) of a sample of 40 people. Along with the paired sample data, the technology was also given a foot length of 27.5 cm tobe used for predicting height. The technology found that there is a linear correlation between height and foot length.

If one wishes to assess the relation between a farming county's average annual temperature and the crop yield, it may be important to take into account the overlapping variability that crop yield and temperature share with rainfall. To do so, one would compute a: a. partial correlation. b. split-half reliability. c. concurrent validity. d. coefficient alpha.
A university would like to describe the relationship between the GPA and the starting monthly salary of a graduate who earned a business degree from the university.
