At an antique boat show, 90% of the boats are made of a natural, polished wood. 75% of the boats have some chrome accents on the boat on at least one visible feature. And 60% have both features.

Does it appear that having chrome accents and being made of wood are independent characteristics? Provide statistical evidence to justify your response.
