Consider Two Normal Distributions

Multiple Choice

Consider two normal distributions. Normal Distribution A has = 50 and s = 4. Normal Distribution B has = 15 and s = 2. How does the total area under the curve differ between Distribution A and Distribution B when we move from the mean to +1 standard deviation along the curve's horizontal axis (abscissa) ?

A) The area is half as large for Distribution A compared to Distribution B.
B) The area under the curve is equal for Distribution A and Distribution B.
C) The area is twice as big for Distribution A compared to Distribution B.
D) The area is four times as big for Distribution A compared to Distribution B.
