b) What statistical test is appropriate for these hypotheses?

c) Draw a scatterplot. How would you describe the relationship between the two variables – linear, non-linear, curvilinear?

d) The calculated r value is 0.62. How do you interpret this data. Describe the direction and strength of the relationship.

e) The value of r for two-tailed probabilities (α= 0.05) for sample size of 14 is 0.53. What is your conclusion based on the results?
