Question

the table shows the shipping costs for items of different values. which best describes the strength of the model? shipping costs for items total cost of items shipping costs $25 $5.99 $45 $8.99 $50 $8.99 $70 $10.99 a weak positive correlation a strong positive correlation a weak negative correlation a strong negative correlation

Explanation:

Step1: Observe the trend

As the total cost of items increases ($25, $45, $50, $70), the shipping costs also increase ($5.99, $8.99, $8.99, $10.99). So it is a positive - correlation.

Step2: Analyze the strength

The increase in shipping costs is not very steep with the increase in item cost. There is not a very tight linear relationship. So it is a weak positive correlation.

Answer:

a weak positive correlation
