Let
µ1 =The mean examination score for the population of individuals trained at center A
µ2 =The mean examination score for the population of individuals trained at center B
A B
Sample Size 30 40
Sample Mean 82 78
Standard deviation 10 10
(Based on previous studies)
Can we conclude using a = .05 that the training quality in center A is better than the training quality in center B?
