Question

(a) a computer manufacturer conducted a survey. it showed that a younger customer will not necessarily purchase a lower or higher priced computer. what is likely true?
there is no correlation between age and purchase price.
there is a correlation between age and purchase price. there may or may not be causation. further studies would have to be done to determine this.
there is a correlation between age and purchase price. there is probably also causation. this is because there is likely a decrease in the purchase price with a decrease in age.

Explanation:

The survey shows younger customers don't necessarily buy lower or higher - priced computers. Correlation implies a relationship (like as one variable changes, the other does in a predictable way). Since younger customers' purchase prices don't follow a pattern (not necessarily lower or higher), there's no correlation between age and purchase price. The other options suggest a correlation exists, which doesn't match the survey result.

Answer:

There is no correlation between age and purchase price.
