An internal report on customer service efficiency includes a bar chart showing average call handling time (in minutes) for the past four quarters. Q1: 6.5 min, Q2: 7.2 min, Q3: 5.8 min, Q4: 6.0 min. The report also mentions a new training program was implemented at the beginning of Q3. What can be inferred about the effectiveness of the training program based on this data?

The correct answer to the question "An internal report on customer service efficiency includes a bar chart showing average call handling time (in minutes) for the past four quarters.
