Question: For each data set given in 10a and b, draw a scatter plot and find the correlation coefficient, r. State what this value of r
a. {(0.3, 0.9), (0.4, 0.6), (0.6, 0.4), (1, 0.3), (1.4, 0.4), (1.6, 0.6), (1.7, 0.9), (0.3, 1.1),
(0.4, 1.4), (0.6, 1.6), (1, 1.7), (1.4, 1.6), (1.6, 1.4), (1.7, 1.1)}
b. {(0.4, 1.4), (0.6, 1.1), (0.8, 0.8), (1, 0.5), (1.2, 0.8), (1.4, 1.1), (1.6, 1.4)}
c. For the data sets in 10a and b, does there appear to be a relationship between x- and y-values? Is this reflected in the values you found for r?
