A normal bell curve labeled Upper A and a normal elongated curve labeled Upper B are centered at the same point. Normal curve Upper B is narrower and above normal curve Upper A.
Select all that apply:
We are given that the both the normal curves A and B are centered at the same point. Therefore, both the curves have same mean. Also, we are given that the normal curve B is narrower than the normal curve A. Therefore, the normal curve A has larger standard deviation.
Therefore, the correct options are:
The means of A and B are equal.
