To determine if carrot juice helps improve heart conditions, a juicing company asks a random sample of 100 adults about whether

or not they drink carrot juice and their heart condition. The company finds an association between drinking carrot juice and healthy heart conditions.
Which statement is true about a possible confounding variable?

A possible confounding variable is the amount of exercise. Those that drink carrot juice may be more concerned about their health and exercise more, which explains the healthy heart conditions.

A possible confounding variable is eating dinner at a fast-food restaurant. Those that eat at fast-food restaurants are more likely to not drink carrot juice and the fast food would explain the healthy heart conditions.

A possible confounding variable is the amount of exercise. Those that drink carrot juice are not concerned about their health and are more likely to not exercise, which does not improve heart conditions.

A possible confounding variable is eating fast food. Those that drink carrot juice are more concerned about their health and are more likely to not eat fast food which does not improve heart conditions.

The answer would be 12, 8, 0, -3, -4.

The answer is that because 12 is a positive number so that's higher than negative, 8 goes second because its positive and higher than the others, 0 is third because negatives numbers are LOWER than 0, not higher, -3 is next because higher negative numbers are always lower, not greater than smaller numbers because -8 is LOWER than -4 since its on the left of a number line.
