When you get a surprisingly low price on a product do you assume that you got a really good deal or that you bought a low-quality product? Research indicates that you are more likely to associate low price and low quality if someone else makes the purchase rather than yourself. In a similar study, 16 participants were asked to rate the quality of low-priced items under two scenarios: purchased by a friend or purchased yourself. The results produced a mean difference of 2.6 and a SS = 135, with self-purchases rated higher. Is there evidence that the judged quality of objects significantly increase for self-purchases than for purchases made by others? Please use a one-tailed test with level of significance of 5%.
