Answer the following statement(s) true (T) or false (F)

1. Engineering presentations are typically verbal reports and rarely include calculations, graphs, charts, and engineering drawings. 2. In a formal presentation there are certain rules and strategies that you need to follow. 3. Your oral presentation may show the results of all your efforts regarding a project. If the listener cannot follow how a product was designed or how the analysis was performed, then all your efforts become insignificant. 4. The oral technical presentation in many ways is not similar to a written one. You do not need to be well organized and have an outline of your presentation ready, similar to the format for a written report. 5. It is a good idea to rehearse your presentation and ask a friend to listen and provide suggestions about your style of presentation, delivery, and content of the talk.
