1 Explain HOW you would use the scientific method to test which helps kids lose weight:...
please answer questions clearly Part 3: Which Test Should You Use? scenarios. Your task is to determine which statistical test is most appropriate a), and to explain why you chose that statistical test (part b). Consider things variables, scores vs. frequencies, number of groups, and what we know (or don not Below are 8 research Directions: Below are8 to test each research like continuous vs. nominal know) about various populations Your which statistical test to use. There are 12 options...
explain in detail, how the scientific method influences two electrical engineering biased test procedures.(stress tests, crash tests, eddy current tests, ultrasonic tests, liquid penetration 'etc')
If you were grading a set of exams dealing with the scientific method, which statement would lead to a student losing points?
What is the time-inconsistency problem (use an example if that helps you explain it)? How do nominal anchors “solve” the time-inconsistency problem for central bankers?
1 and 2 please 1. Explain why you would conduct a t test rather than a z test. In other words, what is the difference between a one sample t test and a one sample z test? 2. Because of what is discussed in question 1, some of the components of calculating at value are different from the components of a z value. Specifically, the t value utilizes degrees of freedom. Explain what degrees of freedom means (you can include...
We need continuity method 5. Explain continuity and how you would use it to solve the deflection of this beam. El is constant. (15 points) 8 kN/m 12 KN 50 kN.m B -5 m
How does a researcher find quality scientific articles? What are some databases that you would use? What are some poor examples of sources?
I am not sure which test I would use or how to enter the data in statdisk on the problem below. Scenario 4: Drug Effectiveness To test the effectiveness of a new drug, a researcher gives one group of individuals the new drug and another group a placebo. The results of the study are shown below. At the 0.01 level of significance, can the researcher conclude that the drug is effective? In other words, are the results independent of the...
Explain how soluble fiber helps to lower cholesterol. Name 2 food that you would add to your diet that are high in soluble fiber.
Write the null and alternative hypotheses you would use to test the following situation. A weight loss center provided a loss for 72% of its participants. The center's leader decides to test a new weight loss strategy to see if it's better. What are the null and alternative hypotheses? Ho: p-0.72 HA p # 0.72 Ho: p = 0.72 HA: p<0.72 Ho: p = 0.72 HA: p>0.72 Ho: p > 0.72 Ha: p = 0.72 Ho: p> 0.7.2 HA: p...
