electronic equipment is interested in determining
whether different training methods have an effect on the productivity
of assembly-line employees. She randomly assigns
21 of the 42 recently hired employees to a computerassisted,
individual-based training program. The other 21
are assigned to a team-based training program. Upon completion
of the training, the employees are evaluated on the
time (in seconds) it takes to assemble a part. The results are
in the data file which is attached.

individual-based program and those trained in a teambased
program?
