Final answer:
Test plans do require the collaboration of end users and information systems specialists to ensure both user requirements and technical considerations are met. Experiments can be done on humans ethically, and larger sample sizes in scientific experiments are preferable.
Step-by-step explanation:
Test plans do indeed require input from both end users and information systems specialists. This is because creating an effective test plan necessitates a clear understanding of user requirements and the technical aspects of the system. End users provide insights into how they expect the system to operate and the necessary functions it should perform. Information systems specialists bring technical expertise to the table, ensuring that the system's infrastructure can support user requirements and that all technical aspects are accounted for in the plan. Collaboration between these two groups helps in designing comprehensive test plans that cover all necessary scenarios.
In the context of the additional information provided, it is false that experiments cannot be done on humans. Human-based experiments are actually a cornerstone of clinical research, provided they are conducted ethically and with strict adherence to regulatory standards such as informed consent and review by ethics committees. Furthermore, it is true that larger sample sizes in scientific experiments are generally better than smaller ones. Larger samples can reduce the impact of outliers and provide a more accurate representation of the population, thereby increasing the reliability and validity of the experimental results.
