Four different assembly processes were under consideration. Thirty-two workers were randomly assigned to the four processes, four per processes

1. 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:

a. What is the value of SS_F

b. What is the value of SS_T

c. What is the value of SS_E

a. With the = 0.01, is there a significant difference between the four processes?

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
