When you get a surprisingly fow price on a product do you assume that you got a really good deal or that you bought a low-quality product? Research indi- cates that you are more likely to associate low price and low quality if someone else makes the purchase rather than yourself (Yan & Sengupta, 2011). In a similar study, n = 16 participants were asked to rate the quality of low-priced items under two scenarios: purchased by a friend or purchased yourself. The

please make it copyable so I can copy and paste it to my notes don't do it on paper. thank you!!

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 (Yan & Sengupta, 2011). In a similar study, \( n = 16 \) 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 \( M_D = 2.6 \) and \( SS = 135 \), with self-purchases rated higher. a. Is the judged quality of objects significantly different for self-purchases than for purchases made by others? Use a two-tailed test with \( \alpha = .05 \).

**Research on Sleep Deprivation and Problem-Solving Ability** Research has indicated that losing even one night's sleep can significantly affect performance on complex tasks, such as problem-solving (Linde & Bergstroem, 1992). To illustrate this phenomenon, a sample of \( n = 25 \) college students was given a problem-solving task at noon on one day and again at noon the following day. The students were not allowed to sleep between the two tests. For each student, the difference between the first and second score was recorded. For this sample, the students averaged \( M_D = 4.7 \) points better on the first test with a variance of \( s^2 = 64 \) for the difference scores. **Analysis Task** a. Do the data indicate a significant change in problem-solving ability? Use a two-tailed test with \( \alpha = .05 \).
