Step-by-step explanation:
Draw a generic normal curve. Subdivide the x-axis on each side of the center (mean) into four approx. = parts.
Label the mean with '50.'
1 std. dev. below the mean would be 50-2 = 48;
2 std. dev. would be 48-2= 46, and
3 std dev. would be 46 - 2 = 44
Do the same on the other side of the mean.
The 3 corresponding values will be 52, 54 and 56.
The answer is A. Those are the four points that are graphed.
