Question

1. food sales (scatterplot)

a. a positive correlation occurs when one set of values increases and so does the other set of values.
which food shows a positive correlation between sales and temperature?

which shows no correlation?
b. how could a park manager use this type of information?

Explanation:

For part a:

1. Positive correlation means as temperature rises, sales rise. The ice cream scatterplot shows this upward trend.
2. No correlation means no clear upward/downward trend. The coffee scatterplot has points with no consistent pattern.

For part b:
Managers can use this data to adjust inventory, staffing, and promotions based on expected temperatures to maximize sales and efficiency.

Answer:

a.

• Food with positive correlation: Ice cream
• Food with no correlation: Coffee

b.
A park manager can use this information to stock more of the appropriate food (e.g., more ice cream on warm days, more hot drinks on cooler days), adjust staffing levels for food stands based on expected demand, and plan promotions aligned with temperature-driven sales trends.
