Homework Help: Distributions problem

  1. Jan 4, 2005 #1
    Could someone please tell my how I would determine the area within 0.5 standard deviations of a given z-value? The first one is z=0. What do I need to do?

    If P(z) is the cumultive probability then P(z+0.5) - P(z-0.5) will give you the desired area.
