Answer:

greater than

Step-by-step explanation:

The standard deviation of a distribution σ = \sqrt{sum(x - mean)^2/ n}

where x is the score of each student

Adding 5 to 10 student scores would be = x+5 - mean

increasing the scores of the 10 students by 5, which in turn increases the standard deviation of the distribution.
