The Department of Motor Vehicles evaluates the effectiveness of two different training programs on employee productivity. Productivity scores are measured after the training. Each training program is now assigned to 500 employees. • Program X: Mean productivity score = 85, Standard deviation = 8 • Program Y: Mean productivity score = 83, Standard deviation = 8 • p-value from statistical test (t-test): 0.01 a) Given the p-value, can we conclude that there is a statistically significant difference between the two training programs? Why? b) Program X’s mean score is 2 points higher than Program Y’s, discuss whether this difference is practically meaningful to the DMV.
