Question

john sells frozen fruit bars at a stand in a park during the summer months. he records the average weekly temperature and number of frozen fruit bars sold for 6 weeks. what type of correlation exists between the temperature and the number of fruit bars sold? what is the real - world meaning of the slope of the line of best fit for the given scenario? there are approximately more fruit bars sold for every degree(s) the temperature rises

Explanation:

Step1: Analyze the correlation

As the temperature increases, the number of fruit bars sold also generally increases. So, there is a positive correlation.

Step2: Calculate the slope concept

The slope of the line of best fit in a regression of \(y\) (fruit - bars sold) on \(x\) (temperature) represents the change in \(y\) for a unit change in \(x\).

Answer:

• Positive correlation
• There are approximately \(1\) more fruit bar sold for every \(1\) degree the temperature rises.
