Answer

median = $95$

Work Step by Step

Arrange the scores from least to greatest to obtain: $91, 93, 95, 95, 97, 99$ There are six numbers. The middle numbers are the third and the fourth scores, which are both 95. The median will be the mean of these two numbers. Thus, median = $\dfrac{95+95}{2} = \dfrac{190}{2} = 95$
