It would help if you proofread your questions before you posted them. With 10 scores listed, I assume 5 failed.

The five who have failed must have scores below the lowest passing score. Arrange in order of value.

x,x,x,x,x,4,5,6,6,7,7,8,8,9,9.

If you are not evaluating within the interval, the median = 6
