For each research situation described below, decide what statistical procedure would most likely be used to answer the research question posed. Assume all assumptions have been met for using the procedure.

Q1. Do college grade point averages differ for male athletes in major sports (e.g., football), minor sports (e.g., swimming), and intramural sports?

a. Test the difference between two means (independent samples).
b. Test one mean against a hypothesized constant.
c. Test the difference in means between two paired or dependent samples.
d. Test for a difference in more than two means (one way ANOVA).
e. Test that a correlation coefficient is not equal to 0 correlation analysis.
f. Use a chi-squared test of association.
g. Construct Confidence Interval(s).

Q2. Does knowing high school seniors' IQ scores indicate anything about their high school graduation grade point averages?

a. Test one mean against a hypothesized constant.
b. Test the difference between two means (independent samples).
c. Test that a correlation coefficient is not equal to 0 correlation analysis.
d. Test for a difference in more than two means (one way ANOVA).
e. Test the difference in means between two paired or dependent samples.
f. Use a chi-squared test of association.
g. Construct Confidence Interval(s).

Q3. Is there a relationship between a person's sociability and cheerfulness? (Assume sociability and cheerfulness can be measured by valid and reliable instruments.)

a. Test one mean against a hypothesized constant.
b. Test the difference between two means (independent samples).
c. Test the difference in means between two paired or dependent samples.
d. Test for a difference in more than two means (one way ANOVA).
e. Test that a correlation coefficient is not equal to 0 correlation analysis.
f. Use a chi-squared test of association.
g. Construct Confidence Interval(s).
