You collect data on college professors to assess whether there is a correlation between their self- reported job satisfaction (Y) and the number of courses they teach online (X). You find that these data are correlated at r = -.31, p<.05. Please use this scatterplot to answer the following questions. 1) Based on these data, can you use the number of online courses to predict levels of job satisfaction? Why or why not?
