Question: Directions: 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.

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

I. What are the two variables of interest? What linear relationship are you interested in exploring?

II. Which data collection technique will be used and why is it best?

III. What sample size is best for this data set and why?

IV. Collect the data. Explain any issues you had during data collection. Include the JMP data file with your submission.

V. Is there a statistically significant relationship between the two variables? Describe the relationship in terms of strength and direction. Show your work by including the JMP output file.

VI. Develop a linear model of this relationship. Include the JMP output file.

VII. Is this a valid model to describe this relationship? Describe the fit of the model. Include the JMP output file.
