What does the first data have to do with the statements that follow?
The first three statements (a, b, c) apply to any distribution.
First quartile = 25th percentile
Median = second quartile = 50th percentile
Third quartile = 75th percentile
d would depend upon whether there were any gaps in the score values, the size of the gaps and where these gaps were.
The range = highest score  lowest score.
I hope this helps you to find your answers.
