LOS 10.l: Define the standard normal Session Unit 3:
distribution, explain how to standardize a 10. Common Probability Distributions
random variable, and calculate and
interpret probabilities using the standard
normal 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%.
