A recent study was conducted to analyze the purchasing habits of consumers at a grocery store over the course of one month. The following data points were recorded for a random sample of 100 customers:
- 45% of customers purchased fresh produce.
- 35% of customers purchased dairy products.
- 20% of customers purchased both fresh produce and dairy products.
Based on this data, what can be concluded about the relationship between customers who purchased fresh produce and those who purchased dairy products?
