Here, the <em>standard deviation </em>is the best measure of the spread of a data set. The higher the standard deviation, the more spread out the distribution is. In this case, the distribution with the highest standard deviation (and therefore the greatest spread) is Distribution 3. Its low mean might be deceptive, but the value of a data set's mean has no effect on its spread.
Slope=(y2-y1)/(x2-x1)
(x,y)
(3,1)
(-2,5)
x1=3
y1=1
x2=-2
y2=5
slope=(5-1)/(-2-3)=4/-5=-4/5
slope=-4/5
answer is B
