What is the simpliest  way to explain the following question to me so I can write an essay: Provide two scenarios: one where a Type I error occurs and another where a Type II error occurs. What factors influence the magnitude of risk for each of these and what practices might a researcher engage to minimize these risks? If the null hypothesis is incorrectly reported as significant, which type of error is occurring and what might the subsequent implications be? What conclusions, if any, can be drawn from such results?
