BY USING THIS RESEARCH: The average temperature of Hamilton in January 2020 was less than 32°F (0°C). the site: The data is available at Weather in Hamilton in January 2020 (Ontario) - Detailed Weather Forecast for a Month (world-weather. info)] You will need to: A) Applies a better adjustment line that will have to be used on a point cloud and visually classified. B)Determine the best adjusted equation of the line. C) Calculate the correlation coefficient D) The relationship or factor (cause and effect, common cause factor, inverse cause-to-effect relationship, etc.) between at least one pair of variables must be defined and explained in detail. E)Write a conclusion in which you summarize the highlights and the meaning of your results Dont forget to use the image if needed.
- Shortleaf Pines. The ability to estimate the volume of a tree based on a simple measurement, such as the diameter of the tree, is important to the lumber industry, ecologists, and conservationists. Data on volume, in cubic feet, and diameter at breast height, in inches, for 70 shortleaf pines was reported in C. Bruce and F. X. Schumacher’s Forest Mensuration (New York: McGraw-Hill, 1935) and analyzed by A. C. Akinson in the article “Transforming Both Sides of a Tree” (The American Statistician, Vol. 48, pp. 307–312). The data are provided on the WeissStats site. a. obtain and interpret the standard error of the estimate. b. obtain a residual plot and a normal probability plot of the residuals. c. decide whether you can reasonably consider Assumptions 1–3 for regression inferences met by the two variables under consideration.The Table below represents volume and trip cost data from which you are asked to determine the following: d) Volume of drivers paying the optimum toll Value of Trip Average Volume (vph) | to Last Driver Vehicle Trip Entering ($) Traffic Cost to all vehicles by the last driver entering the highway ($) Cost ($) 2725 6.06 4.00 0.00 3000 5.75 4.00 0.00 3250 5.44 4.07 0.09 3500 5.13 4.18 0.25 3750 4.82 4.32 0.50 4000 4.5 4.50 0.80 4250 4.19 4.72 1.19Differentiate phenomenological from mechanistic modeling.

- I want to examine the relationship between gas mileage of cars and the engine size (displacement in cubic inches). Which explanatory variable is Engine size Gas mileage Relationship between the two Both engine size and gas mileage Neither engine size nor gas mileageThe owner of a moving company typically has their most experienced manager predict the total number of labor hours that will be required to complete an upcoming move. The approach has proven useful in the past, but the owner has their business objective of developing a more accurate method of predicting labor hours. In a preliminary effort to provide a more accurate method, the owner has decided to use the number of cubic feet moved as the independent variable and has collected data for 36 moves. The data is seen below: Hours Feet 24.00 545 13.50 400 26.25 562 25.00 540 9.00 220 20.00 344 22.00 569 11.25 340 50.00 900 12.00 285 38.75 865 40.00 831 19.50 344 18.00 360 28.00 750 27.00 650 21.00 415 15.00 275 25.00 557 45.00 1028 29.00 793 21.00 523 22.00 564 16.50 312 37.00 757 32.00 600 34.00 796 25.00 577…3.)
