Questions: Consider a possible linear relationship between two variables that you would like to explore.

1. Define the relationship of interest and a data collection technique.

2. Determine the appropriate sample size and collect the data.

3. Perform the appropriate analysis to determine if there is a statistically significant linear relationship between the two variables. Describe the relationship in terms of strength and direction.

4 .Construct a model of the relationship and evaluate the validity of that model.

Answer each question with complete sentences and include all relevant JMP files requested.
