Question

(For Questions 25 -27). A consumer group wanted to determine if there was a difference in customer perceptions about prices for a specific type of toy depending on where the toy was purchased. In the local area there are three main retailers: W-Mart, Tag, and URToy. For each retailer, the consumer group randomly selected 5 customers, and asked them to rate how expensive they thought the toy was on a 1-to-10 scale (1= not expensive, to 10 = very expensive). The toy was priced the same at all retail stores.

The data collected is reported in the table below.

W-Mart	Tag	URToy
8	5	4
9	4	2
10	6	1
9	3	5
9	5	4
M_W= 9	M_T= 4.6	M_U= 3.2
SS_W= 2	SS_T= 5.2	SS_U= 10.8
