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 10-
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?
