Answer 1

Here' the answer to the question. Please don't hesitate to give a "thumbs up" in case you're satisfied with the answer

9. The purpose of a Pareto graph is to separate the significant aspects of a problem from the trivial ones. By graphically separating the aspects of a problem, a team will know where to direct its improvement efforts. Reducing the largest bars identified in the diagram will do more for overall improvement than reducing the smaller ones.

So, whereas the bar-graph will not help you to concentrate efforts on factors that matter the most, the pareto graph by its design
will help you channel efforts on things/factors more influential
