Which scatterplot below shows the listed prices of the rings on the weights of the rings? A. B. C. D. Does there seem to be a linear trend? A. No, because the scatterplot shows an obvious curved line. B. Yes, because the scatterplot shows an approximate linear pattern. C. Yes, because the scatterplot does not show any obvious pattern. D. No, because the scatterplot does not show any obvious pattern. (b) Estimate the linear equation using least squares. Interpret the fitted intercept and slope. Be sure to include their units. Note if either estimate represents a large extrapolation and is consequently not reliable. Complete the equation for the fitted line below. Estimated Price (local dollars) =+ Weight (carats) (Round to two decimal places as needed.) \begin{tabular}{|c|r|} \hline \multicolumn{1}{|c|}{ Weight (carats) } & Price (dollars) \\ \hline 0.35 & 1,044 \\ 0.21 & 568 \\ 0.14 & 304 \\ 0.12 & 145 \\ 0.30 & 893 \\ 0.38 & 1,166 \\ 0.23 & 597 \\ 0.35 & 1,023 \\ 0.26 & 724 \\ 0.13 & 179 \\ 0.25 & 688 \\ 0.13 & 267 \\ 0.29 & 792 \\ 0.35 & 1,077 \\ 0.30 & 815 \\ 0.33 & 1,019 \\ 0.37 & 1,097 \\ 0.15 & 330 \\ 0.28 & 793 \\ 0.28 & 765 \\ \hline \end{tabular} Print Done Which scatterplot below shows the listed prices of the rings on the weights of the rings?
