Question

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.

1. What kind of statistical test should be used to test the consumer group's research goal, assuming that the researcher wanted to use the 1-to-10 scale as a numerical interval measure?

A. Repeated-measures t-test

B. One-way Independent Measures ANOVA

C. Repeated-measures ANOVA

D. Independent-measures t-test

2. State the hypothesis that aims to test the consumer group’s research goal (i.e., what is H₀ and H_A).

The data collected is reported in the table below.
