On average, Jack consumes 2400 calories per day. If we know that for the general population, the distribution of calories consumed per day has a mean = of 2000 calories and a standard deviation = of 200 calories, how would you use the empirical rule to interpret the calories consumed by Jack? Are the calories Jack consumes per day very high? Show the necessary steps and your interpretation below.
