A typical plot of the standard normal distribution is shown in the figure below.
The curve is symmetric about z = 0, and the total area under the curve is 1.
It follows that if the value of z is negative, the area to the left of z will be less than 0.5.
Answer: The area to the left of z is less than 0.5000
