4. The manager of a company wants to investigate job satisfaction among its employees. One morning after a meeting she talks to all 25 employees who attended. Does this sampling plan result in a rando?

No, this sampling plan does not result in a random sample. Since the manager only speaks to the 25 employees who attended a specific meeting, the sample is not representative of the entire employee population, as it may exclude those who were absent or not invited to the meeting. A random sample would require selecting employees from the entire workforce without bias, ensuring every individual has an equal chance of being included.
