Final answer:
The question does not provide enough context or data to calculate a 'residual,' as it typically refers to the difference between observed and predicted values in statistical analysis. More information on a predictive model or known relationship between crude oil and jet fuel costs would be needed to address residuals in this scenario.
Step-by-step explanation:
The term 'residual' in mathematics often relates to the difference between observed and predicted values in a regression model or context of statistical analysis. However, the question at hand does not provide a predictive model or context where a residual would be relevant or computable. Instead, it states two absolute prices for crude oil and jet fuel without any information on expected or predicted costs. Therefore, rather than calculating a residual, the question may be misconstrued or lacking the necessary detail. To properly address residuals, more context is required such as a predictive model or known relationship between the cost of crude oil and jet fuel.
Historically, crude oil prices have fluctuated due to various factors such as economic stresses and geopolitical events, impacting the derivatives like jet fuel. These price oscillations and their effects can sometimes serve as pivotal points in larger market trends. In cases where statistics and predictive models are applied to understand and forecast these price movements, residuals could be calculated as the difference between the actual prices and those predicted by the model.
