Learning Objective
I can use Table A to find probabilities associated with a standard normal distribution.
- 1
The standard normal distribution (z-distribution) has a mean (µ) of 0 and a standard deviation (σ) of 1.
- 2
To convert a value, x, from a normal distribution to a z-score, use the formula z = (x-μ)/σ.
- 3
To find the area between two z-values, subtract the smaller area from the larger area obtained from the z-table.
