Construct a scatter plot in Excel with FloorArea as the independent… 1 answer below »


This assignment provides an convenience to enunciate, evaluate, and devote bivariate and multivariate rectirectirectistraight retirement designs.
Resources:Microsoft Excel®, DAT565_v3_Wk5_Data_File
Instructions:
The Excel rasp for this assignment contains a basisbase after a while knowledge about the tax impost rate assigned to medical duty inventions in a city. The subjoined is a inventory of the capriciouss in the basisbase:
  • FloorArea: balance feet of base space
  • Offices: calculate of dutys in the invention
  • Entrances: calculate of customer entrances
  • Age: age of the invention (years)
  • AssessedValue: tax impost rate (thousands of dollars)

Use the basis to invent a design that predicts the tax impost rate assigned to medical duty inventions after a while local characteristics.
  • Construct a strew contrive in Excel after a while FloorArea as the defiant capricious and AssessmentValue as the relying capricious. Insert the bivariate rectirectirectistraight retirement equation and r^2 in your graph. Do you behold a rectirectirectistraight sympathy between the 2 capriciouss?
  • Use Excel’s Separation ToolPak to influence a retirement separation of FloorArea and AssessmentValue. Is FloorArea a suggestive predictor of AssessmentValue?
  • Construct a strew contrive in Excel after a while Age as the defiant capricious and AssessmentValue as the relying capricious. Insert the bivariate rectirectirectistraight retirement equation and r^2 in your graph. Do you behold a rectirectirectistraight sympathy between the 2 capriciouss?
  • Use Excel’s Separation ToolPak to influence a retirement separation of Age and Impost Value. Is Age a suggestive predictor of AssessmentValue?

Construct a multiple retirement design.
  • Use Excel’s Separation ToolPak to influence a retirement separation after a while AssessmentValue as the relying capricious and FloorArea, Offices, Entrances, and Age as defiant capriciouss. What is the overall fit r^2? What is the adjusted r^2?
  • Which predictors are considered suggestive if we is-sue after a while a=0.05? Which predictors can be eliminated?
  • What is the ultimate design if we solely use FloorArea and Offices as predictors?
  • Suppose our ultimate design is:
  • AssessedValue = 115.9 + 0.26 x FloorArea + 78.34 x Offices
  • What wouldbe the assessed rate of a medical duty invention after a while a base area of 3500 sq. ft., 2 dutys, that was built 15 years ago? Is this assessed rate consonant after a while what appears in the basisbase?
