Question: The accompanying table gives the cost and an overall quality

The accompanying table gives the cost and an overall quality rating for 15 different brands of bike helmets (www.consumerreports.org).
a. Construct a scatterplot using y = quality rating and x = cost.
b. Based on the scatterplot from Part (a), does there appear to be a relationship between cost and quality rating? Does the scatterplot support the statement that the more expensive bike helmets tended to receive higher quality ratings?
