Question

A city recorded data for the monthly average temperature (°C) and the number of ice cream sales: (5, 20), (10, 50), (15, 90), (20, 170), (25, 190). The scatter plot shows that as temperature rises, ice cream sales increase, with points roughly distributed from the bottom-left to the top-right. This indicates a _________ correlation.

Question Analysis
This question assesses the student's ability to recognize and identify negative correlation in a scatter plot. The data points show a clear trend where as one variable (temperature) increases, the other variable (ice cream sales) increases.

Key Concept Explanation
Positive correlation occurs when an increase in one variable is associated with an increase in the other variable. In a scatter plot, this is represented by data points that trend from the bottom-left to the top-right.

Step-by-step Solution
1. Identify the trend in the data points: (5, 20), (10, 50), (15, 90), (20, 170), (25, 190).
2. Observe that as the temperat...
