Question

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

Explanation:

Step1: Analyze the data trend

As the total cost of items increases ($25, $45, $50, $70), the shipping costs ($5.99, $8.99, $8.99, $10.99) also generally increase.

Step2: Determine correlation type

Since both variables (total cost of items and shipping cost) move in the same direction (increase together), it is a positive - correlation. Also, the change in shipping cost is not very closely tied to the change in item cost (for example, the jump from $45 to $50 in item cost has no change in shipping cost), so it is a weak positive correlation.

Answer:

a weak positive correlation
