The accompanying data were read from graphs that appeared in an article. The variables shown are the number of acres burned in forest fires in the western United States and timber sales. (Note: the data is the image) (a) Compute the correlation coefficient. (Give the answer to three decimal places.) r=? I need the answer for "r"

y 6 4 2 0 0 2 4 6 8 x Tell whether the data have a positive correlation, a negative correlation, or approximately no correlation.

You generate a scatter plot using Excel. You then have Excel plot the trend line and report the equation and the r2 value. The regression equation is reported as y = - 61.46x + 41.55 and the r? = 0.16. What is the correlation coefficient for this data set? r =
