Step-by-step explanation:

Depends upon what you're looking for!  If you want the area under the standard normal curve to the left of z = -3.49, here's one way to do it on a TI 83 calculator:

normcdf(-100, -3.49).  Because the z-value -3.49 is more than 3 standard deviations below the mean, the area to the left of z = -3.49 resembles 0.002.  Try this on your calculator:  normcdf(-100, -3.49)
