QUESTION 3 An environmental researcher conducts an experiment on the usage of particular chemical to a species of plant in order to see the plant growth. A species of plant is given a drip feed containing a particular chemical and its ooncentration in the plant vessel is measured in suitable units, at one hour intervals. The researcher believe that a linear relationship will exist between the variables. Time, x (hours) Concentration, y 1 4.3 3 6.9 4 9.1 6 13.5 2 2.4 5.0 11.4 Construct a scatter plot between the variables. ii. Compute the value of the correlation coefficient. ii. What is the linear relationship between the variables? iv. i. Find the equation of the regression line. V. Estimate the concentration of the chemical in the plant vessel after 3.5 hours.

pan's high population density has resulted in a multitude of resource-usage problems. One especially serious difficulty concerns waste removal. An article reported the development of a new compression machine for processing sewage sludge. An important part of the investigation involved relating the moisture content of compressed pellets (y, in %) to the machine's filtration rate (x, in kg-DS/m/hr). The following data was read from a graph in the article. x 125.8 98.1 201.4 147.3 145.9 124.7 112.2 120.2 161.2 178.9 159.5 145.8 75.1 151.5 144.2 125.0 198.8 133.9 y 77.9 76.8 81.5 79.8 78.2 78.3 77.5 77.0 80.1 80.2 79.9 79.0 76.9 78.2 79.5 78.1 81.5 71.0 (a) Determine the slope and intercept of the estimated regression line.

Question 4 A company that focuses on research and development (R&D) is interested in the relationship between profit and some variables that can explain profit variations. They want to predict the profits of some new and exciting projects because some are risky. The predictor variables considered are: RISK which is a company derived metric, R&D which is the research and development costs, REGION (WC, EC and KZN) and average per capita income (INCOME in R1000.00). The analyst decides to estimate the regression function with the following response function. (profit) = bo + b₁XRISK + b₂XR&D + b₂XWc + b₁XEC + b₂XINC Answer the following questions. 4.1. The analyst considered the fact that the effects of multicollinearity may influence some analytical and visual conclusions. Use the following results to show the process of establishing by using extra sums of squares whether there is that multicollinearity present or not. Explain and interpret in detail. SSR (X) = 2573.72, SSR(x₁) = 2600.7,…
