Review Chapter 3 of your course text, which
introduces probability and the standard normal
distribution. When comparing data from different
distributions, what is the benefit of
transforming data from these distributions to
conform to the standard distribution? What role
do z-scores play in this transformation of data
from multiple distributions to the standard
normal distribution? What is the relationship
between z-scores and percentages? In your

the proportion of the area under the standard
curve? Give an example that illustrates your

written about the relationship between a
students S.A.T. test scores and their familys
income. Generally speaking, there is a strong
positive correlation between income and S.A.T.
scores. What might this tell you? Is this
evidence that having a high family income causes
one to have high S.A.T. scores? Is this evidence
that high S.A.T. scores are a cause of high
income? Or, does this tell you something else? If
something else, what? In the course of your
response, explain why correlation alone is rarely
sufficient to demonstrate cause.
