    You can use a statistics package such as SciPy for the Python programming language to answer this:

    >>> import scipy.stats
    >>> print scipy.stats.norm.cdf(2.24) - scipy.stats.norm.cdf(0)
    0.48745453856405341

    Hope that helps!

    Two problems with this answer:

    1. The OP won't learn how to find the answer himself, and
    2. You made a typo in your program - he's looking for the z-score of 2.34.

    To the OP: if you Google "z-score table," you can find the answer easily - here's one result:

    The area under the curve is the z-score of 2.34 minus the z-score of 0.
