The director for training at a company that manufactures electronic equipment is interested in determining whether different training methods have an effect on the productivity of assembly line employees. One of his employees who is tasked with testing this assumption randomly assigns 42 recently hired employees into two groups of 21, of which the first receives a computer assisted, individual-based training program and the other receive a team-based training program. Upon completion of the training, the employees are evaluated on the time (in seconds) it took to assemble a part. The results are as follows:

Computer-Assisted, Individual-Based Program Team-Based Program

19.4 20.7 21.8 22.4 18.7 19.3

14.1 16.1 16.8 15.6 18.0 21.7

14.7 16.5 16.2 30.7 23.7 12.3

16.4 18.5 16.7 16.0 13.8 18.0

19.3 16.8 17.7 20.8 17.1 28.2

19.8 19.3 16.0 20.8 24.7 17.4

17.7 17.4 16.8 20.1 15.2 23.2

The director is an avid proponent of computer-assisted training and asserts even before the research study that the computer-assisted training program will produce better outcomes than the team-based training program. (Show excel output and calculations needed to answer these questions.)

State the hypotheses for this study (both null and research).

What would the researcher conclude with these data? Assume a significance level of .05.
