In a study of the effect of mood on the evaluation of nutritious food, 208 subjects were randomly assigned to read either a happy story ( to induce positive mood) or a control (no story, neutral mood) group. Subjects were then asked to evaluate their attitude toward a certain indulgent food on a nine-point scale, with higher numbers indicating a more positive attitude toward the food. The following table summarizes the data: Group n x bar s Positive mood 104 4.25 2.15 Neutral mood 104 5.25 1.75 Test the hypotheses of no difference between two groups using a two-sample t-test. Compare p-value and α=0.05 Describe the test result.
