We wish to estimate (with 99% confidence) the proportion of students take the bus to school. We survey a random sample of 950 students and get the following results: 510 students take the bus, 434 students do not take the bus and 6 students did not respond We should use: O Zinterval 1-PropZint O2-SampTint O2-SampZint O TInterval O 2-PropZint Submit Question

K Do cars get better gas mileage with premium instead of regular unleaded gasoline? It might be possible to test some engines in a laboratory, but we'd rather use real cars and real drivers in real day-to-day driving, so we get 20 volunteers. Design the experiment. ... Determine how the experiment should be carried out. Choose the correct answer below. OA. Have each volunteer use different kinds of gas depending on the trip. Use premium for highway and use regular for back roads. B. Have each of the volunteers use each kind of gas for a month. Randomly assign 10 of them to use regular first and the other 10 to use premium first. OC. Have each volunteer only use one kind of gas for the duration of the experiment. Assign 10 to only use regular and 10 to only use premium. OD. Have 10 of the volunteers not drive their cars and have the remaining 10 volunteers use different types of gasoline, on various roads. Identify the factors, levels, and variables of the experiment. This experiment…

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).
