the table shows the shipping costs for items of different values. shipping costs for items total cost of items $25 $45 $50 $70 shipping costs $5.99 $8.99 $8.99 $10.99 which best describes the strength of the model? a weak positive correlation a strong positive correlation a weak negative correlation a strong negative correlation
Step1: Analyze the data trend
As the total cost of items increases from $25 to $70, the shipping cost increases from $5.99 to $10.99. The increase is not perfectly linear but there is a general upward - trend.
Step2: Determine correlation type
Since the shipping cost increases as the total cost of items increases, it is a positive correlation. Also, the change in shipping cost is not extremely closely related to the change in item cost, so it is a weak positive correlation.
