Answer

Options B and E are correct.

The correct statements include

- B has a larger mean.

- B has a larger standard deviation.

Explanation

The mean of a normal distribution refers to the center of the distribution. It occurs at the center part of the curve where it shoots upwards the most.

So, we can see that the distribution of B has a higher value considering it's further on the right side along the x-axis.

Then, the standard deviation of a normal distribution shows how much the other values spread arount the mean (the center) of the distribution.

Its value is shown in how extended over the x-axis the graph is.

And once again, we can see that the graph of distribution B spreads over a larger area of the x-axis, so, its standard deviation has to be grater than that of distribution A.
