Find the area under the standard normal curve between z = 0 and z = 2.34. Round the answer to 4 decimal places.

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.
