Which of the following statements about the interpretation of correlations is NOT true?
a. Just because two variables are correlated doesn't mean that one necessarily caused the
other.
b. There is nothing in correlation analysis that can be used to establish causality.
c. When you obtain a statistically significant correlation coefficient between two
variables, you can safely assume that one variable caused another.
d. All that analytical procedures can do is measure the nature and degree of association
between variables.
e. Statements of causality must come from underlying knowledge and theories about the
phenomena under investigation.

The NFL office discovered data covering attendance at professional football games in
the late 1940s and early
1950s. The game with the highest attendance was between the St. Louis Cardinals and
the New York Giants. The office also found considerable information that someone had
collected on each game day such as the level of GDP, the Dow, numbers of persons
employed, number of new businesses formed during the week preceding the game,
and the population. A student intern took the information and built a regression model
to predict game attendance for the upcoming season. The model should
a. accurately predict game attendance.
b. NOT predict game attendance accurately because the variable levels of today (i.e.,
population, Dow, etc.) are out of range of those used to build the regression model.
c. predict game attendance accurately because the variable levels of today (i.e.,
population, Dow, etc.) are out of range of those used to build the regression model.
d. predict game attendance accurately because the variable levels (i.e., population, Dow,
etc.) are within range of those used to build the regression model.
e. None of the above.

d. The average value of Y given x = 10 is 370.
e. If X = 0, then Y = 20.
