Week 3 DQ 1
What are the characteristics of a normal probability distribution function
(pdf).
What is the standard normal pdf? How is it related to the normal pdf and
why is it useful?
Explain the Empirical Rule? Is it used for rough estimates or precise
calculations?
Briefly tell how to use Table A-2 in the Appendix of our text to calculate
z-values (Triola, 2006). How is area under the standard normal curve
related to probability? Is the table arranged so that probability is
cumulative from the left or from the right?
