For n = 188 students, the correlation between y = fastest speed ever driven and x = number randomly picked between 1 and 10 is about r = 0. Describe what this correlation indicates about the association between the fastest speed driven and picking a number between 1 and 10. The two variables are not linearly related. A scatterplot will likely show no visible pattern or a pattern that does not look anything like a straight line trend. The two variables are linearly related.
