Final answer:
The exact percent score required to obtain a special learner's permit is not provided, but a high percentile typically indicates a better score on tests. Percentile comparison, such as the 80th percentile equating to 49 points on a 60-point assignment, demonstrates how scores are evaluated within a group. Scoring at least 70 percent on a test by guessing would be improbable without studying.
Step-by-step explanation:
The percent score required to obtain a special learner's permit is not explicitly stated within the provided context. However, from similar questions regarding test performance and percentiles, we can infer that a higher percentile indicates better performance. This would suggest that when talking about licensing or certification, a certain minimum threshold would also be expected to be met. To address the lack of specified correct choice for the permit question, we can give more general knowledge about test scoring.
Percentiles are used to compare scores within a group. So, if for example, we're told an 80th percentile on a 60-point assignment is 49 points, this means that 80 percent of the test-takers scored 49 points or less. In the context of exams or permits, a high percentile typically equates to good performance. Therefore, if we extrapolate this understanding to the permit test, one would likely need to score in a high percentile, although the exact percentage for obtaining a permit is not provided in this context.
Regarding a student's probability to pass a test by guessing, if one had to earn at least a 70 percent, they would need to guess correctly on a high enough proportion of questions to meet that threshold. The probability, however, would generally be quite low without sufficient knowledge of the material.
