Final answer:
The question refers to determining the sample size for a group of loan applications with errors. The correct sample size given in the student's question is 150, and the process involves careful handling of significant figures and rounding.
Step-by-step explanation:
The student has asked about determining the sample size given that 25 samples consisting of 150 loan applications each resulted in 22 applications with errors. To answer this question, we need to understand the concepts of sampling and probabilities. Since the question provides information about rounding rules and significant figures, these would need to be considered in the calculation process.
Although the provided reference information does not directly answer the student's question, we can infer the need for careful calculation and rounding of numerical data. As such, the sample size in the student's question is 150, following the provided scenario and applying rounding conventions as needed.
