Final answer:
Approximately 90% of students successfully move from the first to the second year.
Step-by-step explanation:
The percentage of students successfully moving from the first to the second year can be calculated using the given options. From the options provided, the closest percentage to the answer is 90% (option b). This implies that approximately 90% of students successfully move from the first to the second year.
For example, looking at previous sample questions, if we were considering a scenario where 85 percent of graduating students attend their graduation, and we had a group of 22 graduating students, we could calculate the expected number of students attending. Similarly, if a college professor states that 68 percent of his students pass the final exam, a researcher could design a study to verify this by using methods such as confidence intervals or hypothesis testing.
