(1) At the dispositional hearing, the court shall determine whether it is in the best interests of the minor and the public that the minor be made a ward of the court, and, if the minor is to be made a ward of the court, the court shall determine the proper disposition best serving the health, safety and interests of the minor and the public. The court also shall consider the permanency goal set for the minor, the nature of the service plan for the minor and the services delivered and to be delivered under the plan. All evidence helpful in determining these questions, including oral and written reports, may be admitted and may be relied upon to the extent of its probative value, even though not competent for the purposes of the adjudicatory hearing.
