You have a normal curve with a mean of . You increase the standard deviation of this curve. How does the curve change?

The new normal curve seems"taller" and"thinner."

The new normal curve seems"flatter" and"wider."

The area under the curve within one standard deviation of the mean increases.

The mean increases at the same rate as the increase in the standard deviation.

None of the above
