Explanation / Answer

Question Answer Explanation How hard the rain is falling and your commuting time Positive correlation As hard the rain is falling, visibility will be low and the traffic movement will be slow. Consequently, the commuting time will increase. How often you say no to dessert and your body fat Positive correlation The number of times saying 'no' will increase, if your weight is increasing. The increased weight implies that the fat content in body is increasing. The amount of wine you consume with dinner and your alertness after dinner Negative correlation The more amount of wine you consume, there will be more alcohol content in your body and consequently there would be less alertness after dinner.
