Help part B

The data table found below contains the listed prices and weights of the diamonds in 20 rings offered for sale in a newspaper in a foreign city. The prices are in local dollars with the weights in carats. Complete parts (a) through (g) below. E Click the icon to view the data table (a) Scatterplot the listed prices of the rings on the weights of the rings. Does the trend in the average price seem linear? i Data Table Which scatterplot below shows the listed prices of the rings on the weights of the rings? A. OB. C.
