- Solve the following problems based on the step-by-step procedure of the Non-Parametric Tests. Show complete solutions and answer. When nicotine is absorbed by the body, cotinine is produced. A measurement of cotinine in the body is therefore a good indicator of how much a person smokes. Listed below are the reported numbers of cigarettes smoked per day and the measured amounts of nicotine (in ng/ml). Is there a significant correlation at alpha = 0.05? x (cigarettes/day) 60 10 4 15 10 1 20 8 7 10 10 20 y (cotinine) 179 283 75.6 174 209 9.51 350 1.85 43.4 25.1 408 344For Questions 1 and 2, you will read an operational hypothesis. Identify the independent variable (IV), dependent variable (DV), and unit of analysis (UA). For each variable (IV and DV), indicate the appropriate level of measurement. There is a relationship between political affiliation (on a scale of 1 to 10, where 1 = very liberal and 10 = very conservative) and U.S. geographic regions, such that people living in the Northeast are more likely to consider themselves liberal than people living in the South. IV: DV: UA: Level of Measurement (IV): Level of Measurement (DV):Kindly answer items 1 and 2. Kindly refer to the Empirical rule provided. Thank you.
- I need help with part (c) only, I need t statistic and p value. Mist (airborne droplets or aerosols) is generated when metal-removing fluids are used in machining operations to cool and lubricate the tool and workpiece. Mist generation is a concern to OSHA, which has recently lowered substantially the workplace standard. An article gave the accompanying data on x = fluid-flow velocity for a 5% soluble oil (cm/sec) and y = the extent of mist droplets having diameters smaller than 10 µm (mg/m3): x 88 177 182 354 369 442 970 y 0.39 0.60 0.50 0.66 0.61 0.69 0.92 (a) The investigators performed a simple linear regression analysis to relate the two variables. Does a scatter plot of the data support this strategy? Yes, a scatter plot shows a reasonable linear relationship.No, a scatter plot does not show a reasonable linear relationship.

- The ACF and PACF shown above were calculated using data you have been asked to forecast. Answer the following questions. What do these plots probably indicate? What do these plots indicate about the stationarity of the data? What kind of adjustment is needed before ARIMA (Box Jenkins) type forecasting model can be applied to the data?When performing statistical analyses involving paired data, it is important to account for the pairing (or matching) in the analyses because: Question 8 options: There is likely to be an inherent dependence between the 2 paired (or matched) observations. The paired (or matched) observations are likely to be independent from one another. You will always get smaller p-values. Parametric approaches to data analyses make fewer assumptions than non-parametric approaches.Which of the following tools is most suitable to analyse the relationship between two quantitative variables? a. Cramer's V coefficient b. Contingency tables c. Bar graphs d. Scatter plot
- What statistical test would be most appropriate if you were interested in seeing how religiosity changes in early adulthood? Religiosity was measured using an interval scale, and the same participants provided data at two time points – at age 15 and 25. Assume the data meets all assumptions for a parametric testMy questions are indicated below. Follow up questions for experiment 2: Using the data in Experiment 2, investigate how the RHA addition and the admixture addition affect the concrete compressive strength. a. Do the amount of RHA affect the compressive strength? How so? b. Does the admixture affect the compressive strength? How so? c. How does the variation in RHA and admixture addition affect the compressive strength? Which of them has the stronger influence on the compressive strength? d. Do we have sufficient evidence to identify an optimum % addition that will result to maximum compressive strength? Support your answer or provide recommendations, if not possible to know the optimum % addition. Take your time in answering. I know it is hard. I tried my best to solve this problem, I just want to double check and make sure that my answer is correct. Thank you so much!A river was contaminated with waste materials.
