An investor thinks that investment preference on "real estate" is more than "stock" investment. In order to understand the true population proportion of investors who invest the money on "stock" 1000 investors randomly selected are asked "What is your investment preference as "real estate" or "stock"? 350 of the investors prefer "real estate". Test the hypothesis that preference of stock is at most 45% at 1%? Find the correct answer for the hypothesis and find the correct answer for critical value

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 HA).
