NEED HELP! willing to make brainliest if correct.. The mean score on a test is 50. Which CANNOT be true?

a
Half the scores are 0 and half of the scores are 100
b
The range is 50
c
Half the scores are 25, and half the scores are 50
d
Every score is 50

The answer is B simply because it says it is the mean, meaning it cannot be the range.

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.
