Final answer:
The location of the 80th percentile is between 76 and 100.
Explanation:
The 80th percentile is the value below which 80% of the data falls. To determine the location of the 80th percentile in the given data set, we need to find the value that separates the lowest 80% of scores from the highest 20%.
In the given data set, the 80th percentile is between 76 and 100, since 76 is the value below which 80% of the data falls and 100 is the value below which 80% of the data does not fall.
Therefore, the correct answer is A. 76.
