2-0.98754 with s, "O with (Round to three decimal places as needed.) What is the correct interpretation of the summary values r and s,? Select the correct choice below and fill in the answer boxes to complete your choice. Round to one decimal place as needed.) O A. The value of r? means that the equation describes about % of the variation. The value of means that the standard deviation of the residuals is million dollars. However, the large outliers increase the size of r OB. The value of r? means that the average residual is dollars. The value of s, means that the equation does not describe about % of the variation. However, the large outliers decrease the size of s,. O C. The value of r? means that the equation describes about % of the variation. The value of s means that the average residual is dollars. However, the large outliers decrease the size of ?. d) Inspect the histograms of the x- and y-variables in this regression. Do the shapes of these histograms anticipate some aspects of the scatterplot and the linear relationship between these variables? O A. Both of the histograms are approximately normal, anticipating the approximately linear scatterplot. O B. Both of the histograms are approximately normal, anticipating the scatterplot with no obvious pattern. OC. Both of the histograms are skewed, anticipating the bend in the scatterplot.

For 26 companies operating in several technology industries, the accompanying data gives the expenses on research and development (R&D) and the total assets of the companies. Both values are reported in millions of dollars. Complete parts a through e below. Click the icon to view the data table. (c) Interpret the summary values r and s, associated with the fitted equation. Attach units to these summary statistics as appropriate. Does the value of r seem fair to you as a characterization of how well the equation summarizes the association? = 0.98754 with Se = with %3D (Round to three decimal places as needed.)
