A research team at the Boston City Campus is planning a survey to assess third-year student satisfaction with their HRMM330-1 module. They want to ensure that the sample size they select will provide statistically meaningful results. They are considering various factors such as the level of confidence, the standard deviation of the population, and the tolerable error. What formula should the research team use to determine the appropriate sample size for their survey? Group of answer choices𝐴=𝜋𝑟2𝑛=(𝜎𝑍𝐸)2𝑆=4𝜋𝑟2

How does a researcher determine the appropriate sample size for a quantitative study?  A. By choosing the smallest possible sample size  B. By conducting a thorough literature review  C. By considering the research budget and time constraints  D. By using statistical formulas and power analysis
