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 and 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 mn = 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

b) compute cohen’s d to measure the size of the treatment effect

step-by-step explanation:

step-by-step explanation:

the triangles are similar. therefore the corresponding sides are in proportion:

              cross multiply

            divide both sides by 32

answer: the proof is mentioned below.

step-by-step explanation:

since, given:   lines bc = ef

prove:   lines ac > ef

          statements                                           reason

1. bc=ef                                           1. given

2. ac= ab+bc                                 2. because b is the point between the  

                                                            line segment ac

3.   ac > bc                                       3. because if a line segment is equal to

                                                          the sum of two line segments then it is

                                                          always greater then each of these

                                                          individual line segments

4. ac > ef                                         4. by equality property.
