An Industrial Engineer Wants to Test the Effect of Three

An industrial engineer wants to test the effect of three different ways of assembling a part on the total assembly time.Five people are randomly assigned to each of the three assembly methods,and the total assembly time (in seconds) is recorded.

A) H0: μ1 = μ2 = μ3 = μ4 = μ5 vs.the alternative that not all the person mean times are equal
B) H0: μ1 = μ2 = μ3 vs.the alternative that not all assembly method mean times are equal
C) H0: μ1 ≠ μ2 ≠ μ3 vs.the alternative that all assembly method mean times are equal
D) H0: μmeth = μper vs.the alternative that the method and person mean times are not equal
E) H0: μ1 ≠ μ2 ≠ μ3 ≠ μ4 ≠ μ5 vs.the alternative that all the person mean times are equal
