Final answer:
The number of times a chairperson taps the gavel for the group to stand may be based on tradition or rules of the organization and can vary, with a single sharp tap being a common practice.
Step-by-step explanation:
The question concerns the practice of a chairperson using a gavel to signal specific actions within a formal meeting, such as instructing participants to stand. This is a common procedure in various deliberative assemblies, including courts and legislative bodies. However, the information you've provided does not specify the exact number of times the gavel is tapped for standing. In many formal settings, such as the United States Supreme Court, the number of gavel rap sequences is often based on tradition or the rules of the particular institution. A common practice is one sharp tap to signal attendees to stand, but the specific protocol can vary by organization.
