Range is largest minus smallest:  is largest minus smallest equal to 95?

Is the lowest grade 95?

The median is the middle number, when the data is sorted from smallest to largest. (In the case of an even number of numbers, the median is halfway between the two middle numbers.) Is 95 the median score?

The mode is the number found most often in the data set? Is 95 the number found most often?
