Answer:

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)
