What are the means and standard deviations, statistics homework help
Exercise 16 1. What do degrees of freedom ( df ) mean? Canbulat et al. (2015) did not provide the df s in their study. Why is it important to know the df for a t ratio? Using the df formula, calculate the df for this study. 2. What are the means and standard deviations ( SD s) for age for the Buzzy intervention and control groups? What statistical analysis is conducted to determine the difference in means for age for the two groups? Was this an appropriate analysis technique? Provide a rationale for your answer. 3. What are the t value and p value for age? What do these results mean? 4. What are the assumptions for conducting the independent samples t -test? 5. Are the groups in this study independent or dependent? Provide a rationale for your answer. 6. What is the null hypothesis for procedural self-reported pain measured with the Wong Baker Faces Scale (WBFS) for the two groups? Was this null hypothesis accepted or rejected in this study? Provide a rationale for your answer. 7. Should a Bonferroni procedure be conducted in this study? Provide a rationale for your answer. 8. What variable has a result of t = − 6.135, p = 0.000? What does the result mean? 9. In your opinion, is it an expected or unexpected finding that both t values on Table 2 were found to be statistically significant. Provide a rationale for your answer. 10. Describe one potential clinical benefit for pediatric patients to receive the Buzzy intervention that combined cold and vibration during IV insertion. Exercise 17 1. What are the assumptions for conducting a paired or dependent samples t -test in a study? Which of these assumptions do you think were met by the Lindseth et al. (2014) study? 2. In the introduction, Lindseth et al. (2014) described a “2-week washout between diets.” What does this mean? Why is this important? 3. What is the paired t -test value for mood (irritability) between the participants ’ consumption of high- versus low-aspartame diets? Is this result statistically significant? Provide a rationale for your answer. 4. State the null hypothesis for mood (irritability) that was tested in this study. Was this hypothesis accepted or rejected? Provide a rationale for your answer. 5. Which t value in Table 2 represents the greatest relative or standardized difference between the high- and low-aspartame diets? Is this t value statistically signifiant? Provide a rationale for your answer. 6. Discuss why the larger t values are more likely to be statistically significant. 7. Discuss the meaning of the results regarding depression for this study. What is the clinical importance of this result? 8. What is the smallest, paired t -test value in Table 2 ? Why do you think the smaller t values are not statistically significant? 9. Discuss the clinical importance of these study results about the consumption of aspartame. Document your answer with a relevant source. 10. Are these study findings related to the consumption of high- and low-aspartame diets ready for implementation in practice? Provide a rationale for your answer.

MTH410 Survey Results Fake News Discussion Post
Locate the results of a recent survey that shows at least two variables in a newspaper, magazine, or Internet article. Outline the survey data so that your peers can understand the variables and results, and then identify at least one key formula from this module that you could use to evaluate the data. Provide a brief explanation of why you selected the formula you did and why it matters. Also, explain what the formula is, where it is in the textbook, and clearly define your parameters.Be sure to support your statements with logic and argument, citing any sources referenced. Post your initial response early, and check back often to continue the discussion. Be sure to respond to your peers and instructors posts, as well.Advice: to you this week is to focus on inferences about the differences between two population means or proportions. (Chapter 10) It is just way too easy to get wrapped up in all of the ANOVA formulas (which are not intuitive).The inferences about two means or two proportions are just hypothesis test with slightly more complicated hypothesis statements and test statistics.To set yourself up for success, look for a survey that involves responses from several different groups of people. Then you can set up a hypothesis test (or a test of independence) to compare the responses from the different groups.Textbook infro is attached: This discussion will result in questions after the initional post.

MTH410 CSU Global Probability and Professional Life Questions
Do you use probability in your profession or real life? You most likely do. For example, the chance of rain tomorrow is 27%. We hear similar probabilities in the media all the time. Similar probabilities could be found in other professions. Complete one of the following:(i) Find an example of probability involving “A or B” that is used in your chosen profession or real life. Explain the example. Are the events A and B in your example mutually exclusive? Which Addition Rule formula for P(A or B) applies? Be sure to cite the source of the information clearly.(ii) Using a search engine, find an example of probability involving “A and B” that is used in your chosen profession or real life. Explain the example. Are the events A and B in your example independent? Which Multiplication Rule formula for P(A and B) applies? Be sure to cite the source of the information clearly.(iii) Find an example involving conditional probability that is used in your chosen profession or real life. Explain the example. Be sure to cite the source of the information clearly.
