Of two personnel evaluation techniques available, the first requires a 2-hour test-interview while the second can be completed in less than an hour. The scores for each of the eight individuals who took both tests are given in the table below.

Applicant Test 1 (x) Test 2 (y)

1 76 38

2 90 57

3 60 36

4 71 45

5 93 58

6 106 71

7 55 30

8 88 53

(b) Would you be willing to use the second and quicker test rather than the longer test-interview to evaluate personnel? Explain.

The correlation coefficient is close to 1, indicating that the second and quicker test could be used in place of the longer test-interview.

The correlation coefficient is close to 1, indicating that the second and quicker test could not be used in place of the longer test-interview.

The correlation coefficient is close to1, indicating that the second and quicker test could not be used in place of the longer test-interview.
