    I need some help with z-scores!

    We started Applied Math 30 doing them, however I seem to have forgotten how to correctly calculate the z-score.

    "Cans of pop from a local company have a mean volume of 355ml with a standard deviation of 0.35ml."

    1. Rounded to the nearest hundredth, determine the z-score for a can of pop with a volume of 355.82ml.

    2. Rounded to the nearest hundredth, what is the probability that the volume of a randomly selected can will be between 354ml and 356ml?

    Any and all help is appreciated!!
