Question

Two methods of assembling a television component are under consideration by management. Because of mire expensive machinery requirements, method B will only be adopted if it is significantly shorter than method A by more than a minute. In order to determine which method to adopt a skilled worker becomes proficient in both methods, and is then timed with a stopwatch while assembling the component by both methods. The following data were obtained:

Method A
X1 = 7.72
S1 = 0.67
n1 = 17
Method B
X2 = 6.21
S2 = 0.51
%3D
n2 = 25
