Final answer:
The number of PNA points for a student scoring between the 50th and 76th percentile on an exam cannot be determined without the specific scoring guidelines or rubric of the exam. Percentiles are a statistical measure indicating the distribution of scores in a group, but the correlation to PNA points is not universal and is dependent on the exam's scoring system.
Step-by-step explanation:
The question pertains to the concept of percentiles in statistics, a measure that indicates the value below which a given percentage of observations in a group fall. Specifically, we're examining the number of PNA points (or Point Not Awarded) a student would receive for scoring between the 50th and 76th percentile on an exam.
To determine this, one would need to consult the specific scoring guidelines or rubric provided for the exam, as percentile ranges do not universally correlate to a set number of PNA points without context.
For instance, in an exam where a higher percentile is desirable, a student in the 76th percentile may receive fewer PNA points than a student in the 50th percentile because their score is higher and closer to the best-performing students.
However, without specific information on the scoring system, we cannot give an exact number of PNA points for the percentile range in question.
