There are three major companies who manufacture gaming consoles. The table below shows thatmarket shares of these three companies, based on last year's global sales figures.Market sharePurchase intentionSunny Gameport8%This year, each of these companies is going to launch a new generation of their console. In a survey, arandom sample of console owners were asked, which company's new model they are most likely tobuy. The results of the survey are show below:Answer:Sunny GameportMarcohard Y-Crate65%21NineTendons Swap27%Marcohard Y-Crate213NineTendons Swap113We can use these data to test whether we have enough evidence that the market shares of the threecompanies are going to change. Calculate the test statistic which can be used to test the nullhypothesis that distribution of current buying intentions among console owners are identical to lastyear's market shares. (The result must be accurate within ±0.05).

In 2008, as an advertising campaign, the Nabisco Company announced a "1200 Chips Challenge," claiming that their 18-ounce bag of Chips Ahoy cookies contained an average of at least 1200 individual chocolate chips. Dedicated statistics students at the Air Force Academy (no kidding, they actually did this) purchased some randomly selected bags of cookies and counted the chocolate chips. Data from their sample is given below. %3D 1219, 1214, 1087, 1200 , 1419,1121 , 1325 , 1345 , 1244, 1258 , 1356, 1132, 1191 , 1270, 1295, 1135 Find a 95% confidence interval for the population mean number of chips in a bag of Chips Ahoy Cookies. (Give final answers to 2 decimal place accuracy) ANSWER: It can be stated with 95% confidence that the true population mean number of chocolate chips in a bag of Chips Ahoy Cookies lies in the interval <μ < chocolate chips per bag Based on this confidence interval, is the Nabisco Company justified in making their claim?

A story describing a burger taste test among non-vegetarians was read by 352 high school students. To investigate the effect of the type of burger (veggie or meat) on subject's opinion of whether or not the burger tasted good, each burger had labels of veggie burger, beef burger, or a burger with no label. Each person was asked whether the burger tasted was good or not. Data are given in the accompanying table. Is there evidence that the proportion who believe that the burger tasted good for the three different labels differ? Test the relevant hypotheses using ? = 0.01. (Round your answer to two decimal places.)

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).
