4.Determine whether the graph to the right can represent a variable with a normal distribution. Explain your reasoning. If the graph appears to represent a normaldistribution, estimate the mean and standard deviation.

A bell-shaped curve crosses a horizontal x-axis labeled from 1 to 7 in increments of 1 at two points.

Could the graph represent a variable with a normaldistribution? Explain your reasoning. Select the correct choice belowand, ifnecessary, fill in the answer boxes within your choice.

A.No, because the graph isskewed left.

B.Yes, the graph fulfills the properties of the normal distribution. The mean is approximately

_______and the standard deviation is about ________. (Round to two decimal places asneeded.)

C.No, because the graph isskewed right.

D.No, because the graph crossesthe x-axis.
