Four different assembly processes were under consideration. Thirty-two workers were
randomly assigned to the four processes, four per processes. The numbers of correctly assembled units in an four-hour work shift were recorded:

c. What is the value of SSE |
4. The following results were obtained as part of a simple linear correlation analysis: Y = 97.98 – 4.33x regression sum of squares = 2680. 27. Error sum of squares = 125.40. Total sum of squares = 2805.67. The sample correlation coefficient is : a. -0.9774 b. 0.9553 c. 0.2114 d. 0.0447
