The following data for the dependent variable, y, and the independent variable, x, have been collected using simple random sampling:
x y
10…………………..120
14…………………..130
16…………………..170
12…………………..150
20…………………..200
18…………………..180
16…………………..190
14…………………..150
16…………………..160
18…………………..200
a. Construct a scatter plot for these data. Based on the scatter plot, how would you describe the relationship between the two variables?
b. Compute the correlation coefficient.
