Use a table to find the area to the left of z= -1.67 is 0.0475


The area to the left of z = 0 is 0.5 (you can use a table, but you really don't need to since z = 0 is the center)


Subtract the areas: Big - Small = 0.5 - 0.0475 = 0.4525

Final Answer: 0.4525

The probability associated with z value -1.67 is 0.0475 and probability of z value of 0 is 0.50
The area between these probabilities is 0.5000 - 0.0475 = 0.4525
