I know this:
I know that standard deviation is 2 points and that means that the data is more clustered together. ther is not much of a spread so off of this I would go with choice B
Most of the test scores are between 77 and 81.
C. Half of the test scores are greater than 81 points. wrong > otherwise the standard deviation would be greater
D. The lowest test score is 77 and the highest is 81. Wrong then the mean would not be 79
