WEEK 8 ASSIGNMENT - CASE STUDY: STATISTICAL INFERENCEWeek 8 Assignment - Case Study: Statistical InferenceOverviewThe research department of an appliance manufacturing firm has developed a solid-state switch for its blender that the research department claims will reduce appliance returns under the one-year full warranty by 3%6%. To determine if the claim can be supported, the testing department selects a group of the blenders manufactured with the new switch and a group with the old switch and subjects them to a normal years worth of wear. Out of 250 blenders tested with the new switch, nine would have been returned. Sixteen would have been returned out of the 250 blenders with the old switch. As the manager of the appliance manufacturing process, use a statistical procedure to verify or refute the research departments claim.InstructionsCreate 810 slides, including a cover and a sources list, for a presentation to the director of the manufacturing plant in which you: Summarize the problem with the appliance manufacturing firm's blenders. Propose the statistical inference to use to solve the problem. Support your decision using a scholarly reference. Using Excel:Develop a flowchart for the proposed statistical inference, including specific steps. Compute all statistical calculations using Excel. Place your flowchart in a slide.Determine if you can verify or refute the research department's claim.Choose sources that are credible, relevant, and appropriate. Cite each source listed on your source page at least one time within your assignment. For help with research, writing, and citation, access the library or review library guides.

Your initial post should be 75-150 words in length.Conditional Probability1. If there are 3 green marbles and 4 red marbles in a bag, and you were asked to draw one without looking, what is the probability of drawing one green marble? Please show work 2. If you don't put that marble back, what is the probability of drawing another green marble? Please show work 3. Using the above "marbles in the bag" scenario, what is a conditional probability question that you can make from it? In §4.4 we are introduced to the concept of conditional probability. The notation P(A | B) denotes the probability of event A occurring given that we know event B has occurred.Now consider the Monty Hall Problem introduced in the following video: https://m.youtube.com/watch?v=4Lb-6rxZxx0 4. After watching this video, we know that if we are given the option to switch doors that, probabilistically speaking, it is in our best interest to switch. Why is the probability of winning NOT 50/50 when the contestant is given the opportunity to switch?Please provide original work. No plagiarizing.
