- When the nature of population from which samples is drawn is not known to be normally distributed the data can be analysed with the help of a. Parametric statistics b. Descriptive statistics c. Non-parametric statistics d. None of the above1. When applying one-way analysis of variance (ANOVA), all the following are key assumptions that should be satisfied EXCEPT: A. Samples are obtained independently and randomly from the population defined by the factor level. B. The mean of the samples taken from the population is always equal. C. The population at each factor level is approximately normally distributed. D. The population have a common variance. 4. The sum of squares for treatment (SST) measures: A. the variation above the k sample means. B. the variation below the k sample means. C. the variation between the k sample means. D. the variation within the k sample means. 5. Which of the following is NOT true for the F- distribution? A. It is generally skewed to the left. B. It has two degrees of freedom. C. It is continuous. D. Its units are non-negative. 2. Which of the following components in an ANOVA table are NOT additive? A. Mean squares B. Degree of freedom C. Sum of squares D. It is not possible to tell. 3. The…The average income of a large sample of households is $63,000 and the s.d. is $7,000. Assume that the data is approximately bell-shaped. What percent of these households have incomes between $42,000 and $77,000? Don’t forget to properly justify your answer using the empirical rule.
- Calculate the most appropriate measures of central tendency and dispersion for the following variable. Respondents were asked to rank how likely they would support ending Obamacare on a scale ranging from 0, definitely would not support, to 10, would definitely support. Here are their scores: 0, 0, 5, 5, 6, 8, 10, 7, 1, 2, 3, 0, 4, 5, 1, 9, 10, 7, 1, 2, 0, 6, 8Consider the following data. Solve not using excel or codeChoose the appropriate statistical test. When computing, be sure to round each answer as indicated. A dentist wonders if depression affects ratings of tooth pain. In the general population, using a scale of 1-10 with higher values indicating more pain, the average pain rating for patients with toothaches is 6.8. A sample of 30 patients that show high levels of depression have an average pain rating of 7.1 (variance 0.8). What should the dentist determine? 1. Calculate the estimated standard error. (round to 3 decimals). [st.error] 2. What is thet-obtained? (round to 3 decimals). 3. What is the t-cv? (exact value) 4. What is your conclusion? Only type "Reject" or Retain"
- Explain each of the following concepts and the relevance of each concept in hypothesis testing: normal distribution, point estimate, and parameter.Suppose we want to compare scores (which can take on any value within a specified range) at baseline and at follow-up for a given sample.

Combined ratio gives the higher estimated variance than the separate ratio estimator. A. True B. False ii. The difference estimator is always unbiased in simple random sample. A. True B. False

What is the p valueConsider the following research questions/study scenarios. For each study, discuss the most appropriate methods for describing the data (graphically and numerically). What statistical method would be most appropriate for addressing the research questions? Be sure to provide justification of the statistical method. When a statistical test is needed, provide appropriate null and research hypotheses. A study investigating the effects of second-hand smoke in working environments asked the following question: “How often do you experience second-hand smoke in a work environment/function? Never, Occasionally, Fairly Often, Very Often, Almost Always.” The question was asked of managers and employees to determine whether there was an association between position and the amount of second-hand smoke exposure. The responses to the questions were grouped into Little/Non and Often, where Little/None was defined as responses of Never or Occasionally and Often was defined as responses of Fairly…
