AMakes it taller or shorter
BMakes it wider or thinner
CSlides it left or right
DTurns it upside down
Answer & Solution
Correct answer: C. Slides it left or right
1. The mean marks where the line of symmetry stands.
2. Moving the mean moves that line along the horizontal axis.
3. The curve keeps its shape and simply slides left or right.
4. Width and height are controlled by the standard deviation, which has not changed here.
