(SUB-PART C ONLY PLEASE) Each row represents an experimental “run” (in this case, averaged sample of mango wine). Column A shows the run number; Column B shows the percentage of ethanol; Column C shows the amount of glycerol (in g/L); Column D shows the amount of acid (in g/L); Column E shows the temperature of the run (in °C); and Column F shows the pH of the run. Y represents Ethanol of mango wine. 1. Create a scatterplot of the ethanol data for all 20 runs (CREATED) a. Draw a graphical representation of the model that you chose to use. (CREATED WITHIN SCATTERPLOT) b. Comparing the model to your data, evaluate its fit in one or two sentences. (LINEAR MODEL; The conditions to say that the model is a good fit are as given below: To say that the model is the good fit, the coefficient of determination should be high. Atleast one the predictor variables should be statistically significant in predicting the response variable. ) c. Replace the generic Yi = β0 + ε with the information you…
R3.40. Fuel efficiency Wayne Collier designed an experiment to measure the fuel efficiency of his family car under different tire pressures. For each run, he set the tire pressure to either 28 or 32 psi and then measured the miles driven on a high- way (I-95 between Mills River and Pisgah Forest, NC) until he ran out of fuel using 2-liters of fuel each time. He also used two different types of gasoline (regular and premium). To run the experiment he made some alterations to the normal flow of gasoline to the engine. In Wayne's words, "I inserted a T-junction into the fuel line just before the fuel filter, and a line into the passenger compartment of my car, where it joined with graduated 2 liter Rubbermaid bottle that I mounted in a box where the passenger seat is normally fastened. Then I sealed off the fuel-return line, which under normal operation sends excess fuel from the fuel pump back to the fuel tank." a) Identify the factors and the levels in the experiment. b) How many times…

Q4 A train leaves Waterloo and travels westbound. Due to track maintenance, it takes the train 2 hours to travel the first 120 km. Once it leaves the construction zone, the train travels at 140 km/h for the rest of the trip. Let s represent the average speed, in km/h, over the entire trip and t represent the time, in hours, spent travelling after leaving the construction zone. If the average speed of the entire trip is 100 km/h, what is the total distance travelled by the train? O O O O Option 1 450km Option 2 350km O Option 3 Option 3 500km O Option 4 400km
