“A partnership and each of its partners are responsible for the wrongful conduct of a partner acting within the scope of the partner’s authority. You must decide whether a partnership existed in this case. A partnership is a group of two or more persons who own a business in which all the partners agree to share the profits and losses. A partnership can be formed by a written or oral agreement or by an agreement implied by the parties’ conduct.”
