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 (1,2) 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. a. do the data points appear to have a strong linear correlation? no yes

Explanation:

The scatterplot shows most points clustered in the top-right (high x, high y) except one outlier (1,2). Visually, the outlier weakens the apparent linear pattern, so there does not appear to be a strong linear correlation.

Answer:

No
