Statistics question

Mean is 3320 g and Standard deviation is 495 g
Suppose it is know that at General Mercy Hospital,6% of all births exceed 4390g.
suppose that this pas month, general mercy had 105 babies born. What is the probability that
at least 10% of those babies weight more than 4390 g?

Are you sure you wrote this correctly? It seems we have some conflicting information. Provide either the Standard Deviation or the 6% information. Both?
