Answer:
B.
Explanation:
We know that
mean = 48
standard deviation = 6
The values that are at 1 standard deviation of the mean are
48 + 6 = 54
48 - 6 = 42
The values that are at 2 standard deviation of the mean are
48 + 2(6) = 60
48 - 2(6) = 36
The values that are at 3 standard deviations of the mean are
48 + 3(6) = 66
48 - 3(6) = 30
Therefore, we need to find a graph where the labels are 30, 26, 42, 48, 54, 60, and 66.
So, the answer is Option B.
