Questions: For the and y. Click here to view the data set, Click here to view the critical values table. (a) Draw a scatter diagram of the data. Choose the correct gras (b) Compute the correlation coefficient. The correlation coefficient is r= (Round to three decimal places as needed.)

Solution Steps

Given the data set, we need to compute the correlation coefficient \( r \). The formula for the correlation coefficient is:

\[ r = \frac{n(\sum xy) - (\sum x)(\sum y)}{\sqrt{[n\sum x^2 - (\sum x)^2][n\sum y^2 - (\sum y)^2]}} \]

Assuming we have the data points \((x_1, y_1), (x_2, y_2), \ldots, (x_n, y_n)\), we can calculate the necessary sums and then use the formula to find \( r \).
