    Standard Deviation

    Thank you for the two posters that helped me with my last question. I am really struggling with stats and have another question I really need help with:

    Birth weights are normally distributed with a mean of 3419g and a standard deviation of 496g. If a hospital plans on setting up special observation conditions for the lightest 3% of babies, what weight is used for the cutoff separating the lightest 3% from the others?

    I think this has to do with standard deviation and looking up .03 on my z-tables? If so, what happens next? Thank you so much for helping me, I'm so confused.

    You need to find x for P\left(Z<\frac{x-3419}{496}\right)=0.03
