A normal curve table tells you that the probability lying below z= -1 is .1587. This can be interpreted as: A. A random selectio
n from the population has a 15.87% chance of being at or below z= -1 B. 15.87% of the area under the curve lies below z= -1 C. A random selection from the population has a 15.87% chance of being below z= -1. D. 15.87% of the area under the curve lies at or below z= -1 E. All of the above
When it is has a probability value of 0.1587, it means
that 15.87% of the total sample is below z = -1 or there is a chance that the
selected sample has a 15.87% chance of being below z = -1. Actually all the
choices are telling the same thing in different way.
