In a study of the effects of mood on evaluation of nutritious food, 208 subjects were randomly assigned to read either a happy story (to induce a positive mood) or a control (no story, neutral mood) group. Subjects were then asked to evaluate their attitude toward a certain food on a nine-point scale, with higher numbers indicating a more positive attitude toward the food. The following table summarizes data on the attitude rating: Group n S Positive mood 104 4.25 2.05 Neutral mood 104 5.65 1.75 Based on the evidence could we conclude that mood changes attitudes towards food? (test hypotheses at level alpha =0.05).
