Question

An experiment was conducted to verify the effect of training at the managerial level in decision making. Two factors are considered in experiment A: level of training of the individual (if he has training or does not have training) and B: the type of situation for which the individual had to make the decision (normal or emergency situation).

sixteen supervisors were selected and 8 were chosen randomly to receive management training. After receiving the training, 4 trained supervisors were selected and 4 of them were not trained to act in a normal situation. In the same way, the other group of 8 supervisors was taken to act in an emergency situation. The decision made by each individual was monitored by the researcher and evaluated on a scale from 0 to 100. The results are presented in the following table:

Situation(B)	Training Level (A)		total
	Training	No Training
Normal	85 91 80 78	53 49 38 45
Sub-Total	334	185	519
Emergency	76 67 82 71	40 52 46 39
Sub-Total	296	177	473
Total	630	362	992

Will there be significant evidence to conclude that the factors are significant? Test an α = 0.05

Answer 1

We will use MINITAB software to get this answer

The ANOVA table output from MINITAB is

so accordingly p-value method we can see only Training has 0.000<0.05

so we can say only training method is significantly effective in the model at 95% confidence.
