Question
Refer to the accompanying scatterplot. a. Examine the pattern of all 10 points and subjectively determine whether there appears to be a
strong correlation between x and y. b. Find the value of the correlation coefficient r and determine whether there is a linear correlation. c.
Remove the point with coordinates (1,10) and find the correlation coefficient r and determine whether there is a linear correlation. d. What do
you conclude about the possible effect from a single pair of values?
Click here to view a table of critical values for the correlation coefficient.
