There is no "58.5 g"

alis · Answer

It was one of the choices, i just put the arrow there to indicate that i chose it.

adovbush · Answer

Oh I see. Then I would go with 51.5 g

alis · Answer

oh okay, what brought you to that answer?

adovbush · Answer

If the average weight is 55 g and the standard deviation is 4.2 g so it means that they don't accept any egg less than 50.8 g 55 - 4.2 = 50.8 g

Therefore, the answer would be 51.5 g
