Question: The table below lists weights carats and prices dollars of

The table below lists weights (carats) and prices (dollars) of randomly selected diamonds. All of the diamonds are round with ratings of “very good” cut, they all have a color rating of F (“slight color”), and a clarity rating of VS I (“very slightly included”). The values are based on data from the retailer Blue Nile. For diamonds of the type described, is there sufficient evidence to conclude that there is a linear correlation between weights and prices? Do the results also apply to other types of diamonds, such as those with different color and clarity ratings?
