I'm having a hard time with this problem and I would need some help, please? Testing Hypotheses. In Exercises 13–24, assume that a simple random sample has beenselected and test the given claim. Unless specified by your instructor, use either the P-valuemethod or the critical value method for testing hypotheses. Identify the null and alternativehypotheses, test statistic, P-value (or range of P-values), or critical value(s), and state thefinal conclusion that addresses the original claim. 15. Garlic for Reducing Cholesterol In a test of the effectiveness of garlic for loweringcholesterol, 49 subjects were treated with raw garlic. Cholesterol levels were measured beforeand after the treatment. The changes (before minus after) in their levels of LDL cholesterol(in mg/dL) have a mean of 0.4 and a standard deviation of 21.0 (based on data from “Effectof Raw Garlic vs Commercial Garlic Supplements on Plasma Lipid Concentrationswith Moderate Hypercholesterolemia," by Gardner et al., Archives of Internal Medicine,Vol. 167, No. 4). Use a 0.05 significance level to test the claim that with garlic treatment, themean change in LDL cholesterol is greater than 0. What do the results suggest about the effec-tiveness of the garlic treatment?Adults

We've studied two different basic types of research studies, Observational Studies and Experiments. They have similarities and differences in their methodologies, and in some cases it is not practical nor ethical to design a study one way or the other. And this affects the kinds of conclusions the research can ultimately reach. This discussion is designed for students to help each other build a complete understanding, and clearly separate these as two distinct concepts. Discuss the similarities and differences between these, as well as the research conclusions to which they can possibly lead.
Hi. Would anyone be so helpful and answer this question with an explanation on how to get to the answer? Thanks much. I've included a picture of the problem. I hope it suffices. Thanks
Linear Algebra This problem was rejected a few minutes ago. I know and understand Bartleby's honor code. This problem is part of a midterm I have already submitted this morning. I want to ensure my answer is correct, mostly because I was not able to complete part (d) due to the time limit. Per my honor code I would not ask for assistance on a graded problem. I am including my submission. If you would kindly verify my work and maybe aid me in completing part d I would be grateful. Thank you!
So I decide to go to Cinnaholic once day and I buy two cinnamon rolls. I notice that these cinnamon rolls do not appear to be the same size, so naturally I eat the smaller one first and then eat the bigger one. As I am sitting on my couch stuffed from those delicious rolls, I start to think, "I wonder if Cinnaholic makes their cinnamon rolls to the size they claim them to be." Of course I have to go and purchase several rolls, weigh them (in ounces), and eat them. 30 pounds later, I have collected all of my data and tabulated it below: Cinnamon Roll Weight 5.6, 6.3, 6.1, 6.1, 5.9, 5.8, 6.0, 6.0, 6.1, 6.3, 6.3, 6.3, 6.4, 5.8, 5.7. Cinnaholic claims that their Cinnabon rolls are made to weigh 6.1 ounces on average. The mean is 6.0467 Standard deviation: 0.2475
Part c? I'm stuck, I'm just trying to learn problems like these to help me study
Good Evening, Can you please come up with a math problem following the guidelines? i appreciate your time!!
please see the attached question. thanks for your help
A tortoise and hare are competing in a 400-meter race. The arrogant hare gives the tortoise a 220-meter head start. When the start gun is fired, the hare begins running at a constant speed of 3.5 meters per second and the tortoise begins crawling at constant speed of 1.5 meters per second. Take out a piece of paper and read the above problem context again. You will prepare your written work and solutions on your own paper and upload it and the end of this question. Complete the problem solving process by: i. reading and re-reading the problem to identify the quantities in the situation; ii. making a drawing to represent the relevant quantities in the situation; iii. and defining the variable t to represent the number of seconds since the start of the race. a. Define a function f to determine the distance of the tortoise from the finish line in terms of the number of seconds, t, since the start of the race. Preview Solve f(t) = 0 and describe what your solution represents. t = Preview…
The solution is completely off the page. I can't see any of the work or the answer.
How do I solve the following problem?
Netflix made headlines in September 2011 when it split its streaming video service and its DVD by-mail service into two companies. This decision was based on projections that streaming videos will replace DVDs in the future. In this problem, you will explore these projections. Numbers below are close to the correct values, but vary to allow more practice with this idea. Total DVD and Blu-ray disc sales in 2009 were $8.72 billion. For the purposes of this problem, you will combine DVD and Blue-ray disk sales into one category of DVD sales. A study by In-Stat predicted that "physical disc sales will decline by $4.7 billion by 2014," and that "streaming, on the other hand, should grow from its current $2.1 billion to $6.3 billion over the same time period (2009–2014)." What is the slope, including units, of the model for streaming videos?
