Suppose a researcher wishes to use the same data set from Q1 to answer the following question:

Can the average number of years adults have spent in schooling in a state significantly predict crime rate in that state?

A. What is the null hypothesis being tested for this research question in words?(1.5 point)

Null Hypothesis:

B. Create a scatterplot with the outcome variable on the Y-axis. (Note: In SPSS, select "Scatter/Dot" at the bottom of the "Graphs" menu. (1.5 point)

[Paste the scatterplot here.]

C. Examine the scatterplot. Is there a hint of a linear relationship? How do you know? Would there be an upward or downward trend and how do you know? (2 points - 1 point for correctly identifying the relationship, 1 point for explanation)
