A Manufacturer of a New Energy Bar Wants to Determine

A manufacturer of a new energy bar wants to determine if it is cost effective to pay for the use of the American Heart Association (AHA) logo on its packaging. The firm has developed two test packages for the product. One package contains the AHA logo; the other does not. A sample of health-conscious consumers (representing the firm's target market) is invited to select an energy bar from a display that contains several competing brands along with the no-logo package.

A) observation.
