At a factory that produces switches, a batch of 4000 switches has just been produced. To check the quality of the switches, a random sample of 175 switches is selected to test for defects. Of these 175 switches, nine were found to be defective. Based on these results, what is the best estimate you can give for the number of defective switches in the batch of 4000? Show detailed work.

Please help explaining how to answer so I can study for my test. The Farm Program for the Montana State Department of Agriculture needs to choose a sample of farms in order to collect information about land utilization. Montana has 56 counties and the 26,800 farms across the state are currently categorized by county. The program would like to select a random sample of at least 112 farms and record the total acreage and the acreage used for pasture and range for each farm in the sample. Two plans have been proposed: Plan A: The program will randomly select 10 counties from the 56 counties. All farms within the 10 selected counties will be visited by a surveyor who will calculate the total acreage and acreage used for pasture and range. Plan B: The program will randomly select 2 farms from each county. All 112 selected farms will be visited by a surveyor who will calculate the total acreage and acreage used for pasture and range. Which of the following best describes the…

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).
