Question

Suppose you have been hired as a management consultant by a major oil company to help it optimally price gasoline at its service stations. your client has requested that your consulting team expatiate on the factors that impact gasoline prices. one of the members of your​ team, debbie, states that she has noticed that gasoline prices seem to rise in years when a national league baseball team wins the world series.

Answer 1

Correlation doesn't prove causation. Debbie's observation doesn't prove a relationship between oil prices and who wins the world series and therefore should not be included in any recommendation given to the oil company.
