Using the information in the table given, the data models the relationship between weight and shipping cost. Hence ;
3.2 pounds will cost $4.13A scatter plot with a trend line Graph is attached below.The cost of shipping a package which weighs 3.2 pounds will be the cost of packages in the 4 pounds category as it has exceeded the maximum weight for the 3 pounds class. Hence, the cost will be $4.13.
Graphing an independent and dependent variable is can be represented using a scatter plot with each pair of weight and shipping cost denoted by a mark on the graph.
Therefore, the graph of the relationship between weight and shipping cost is attached.
