LOS 10.l: Define the standard normal distribution, explain Session Unit 3:
how to standardize a random variable, and calculate and
interpret probabilities using the standard normal 10. Common Probability Distributions
distribution.
Calculating Probabilities Using z-Values, p. 229
Example: Using the z-table (2): Using the distribution of EPS with μ = $6 and σ = $2 again, what percent of the observed
EPS values are likely to be less than $4.10?
P(EPS < $4.10).
That is, $4.10 is 0.95 SDs below the mean of $6.00.
Step 2 –use table to find z:
F(Z) = (F–0.95) = 0.1711, or 17.11%.
