If the mean of a data set is 75 and the standard deviation is 10, what is the range of scores that fall within one standard deviation of the mean?

How can I solve these kind of questions guys? What's the meaning of one SD from the mean? I am struggling badly.

Range = Mean + SD

So, Range = 75 + 10

Thus, So, Range = 65 to 85
