The Excel file for this assignment contains a database with information about the tax assessment value assigned to medical office buildings in a city. The following is a list of the variables in the database: FloorArea: square feet of floor space Offices: number of offices in the building Entrances: number of customer entrances Age: age of the building (years) AssessedValue: tax assessment value (thousands of dollars) Use the data to construct a model that predicts the tax assessment value assigned to medical office buildings with specific characteristics. Construct a scatter plot in Excel with FloorArea as the independent variable and AssessmentValue as the dependent variable. Insert the bivariate linear regression equation and r^2 in your graph. Do you observe a linear relationship between the 2 variables? Use Excel’s Analysis ToolPak to conduct a regression analysis of FloorArea and AssessmentValue. Is FloorArea a significant predictor of AssessmentValue? Construct a scatter plot…

The exercise involving data in this and subsequent sections were designed to be solved using Excel. Johnson Filtration, Inc. provides maintenance service for water-filtration systems. Suppose that in addition to information on the number of months since the machine was serviced and whether a mechanical or an electrical repair was necessary, the managers obtained a list showing which repairperson performed the service. The revised data follow. Repair Time(hours) Months SinceLast Service Type ofRepair Repairperson 2.9 2 electrical Dave Newton 3.0 6 mechanical Dave Newton 4.8 8 electrical Bob Jones 1.8 3 mechanical Dave Newton 2.9 2 electrical Dave Newton 4.9 7 electrical Bob Jones 4.2 9 mechanical Bob Jones 4.8 8 mechanical Bob Jones 4.4 4 electrical Bob Jones 4.5 6 electrical Dave Newton Ignore for now the months since the last maintenance service (x1 ) and the repairperson…

Create scatterplot using Excel with the following variables: gender: 0 = male, 1 = female. height: in inches. weight: in pounds. First we will create a scatterplot to examine how weight is related to height, ignoring gender. To do that in Excel: Sort the data by gender: Hold down the Control key (Command key on MacOS) and click the A key to select all of the data in the worksheet. Select the Home tab, then the Editing group Sort & Filter -> Custom Sort. In the pop-up window, make sure that My list has headers box is checked and then choose gender from the pull-down menu next to Sort by. Click OK. Now select all of the data in columns B and C, select the Insert tab and in the Charts group choose Scatter. Choose the first scatterplot option (Scatter with only Markers). Now we have a scatterplot, but the data is all on the right of the plot. To fix this: Right-click on the x-axis, and choose Format Axis from the pop-up menu. Make sure that Axis Options is selected on the left, and…

A real estate major collected information on some recent local home sales. The first 6 lines of the database appear in the accompanying table. The columns correspond to the house identification number, the community name, the zip code, the number of acres of the property, the year the house was built, the market value, and the size of the living area (in square feet). Do the data appear to have come from a designed survey or experiment? What concerns might you have about drawing conclusions from this data set? E Click the icon to view the data table. Do the data appear to have come from a designed survey or experiment? O A. It is not clear if the data were obtained from an experiment. They are certainly not from a survey. O B. It is not clear if the data were obtained from a survey. They are certainly not from an experiment. O C. It is not clear if the data were obtained from a survey or an experiment. O D. The data were certainly not obtained from survey or an experiment. What…

The migration pattern of Monarch butterflies are tracked by a catch-and-release method in which individual butterflies are tagged with a circular, lightweight sticker placed carefully on the wings so as not to impede their ability to fly. The sticker contains a unique ID number. Volunteers across the U.S. and South America capture the butterflies, record the IDs if they are tagged, and release them. This allows us to track the locations each unique ID is found, allowing us to estimate the migration pattern. On average, 1 out of 100 captured butterflies are already tagged. Suppose you are a volunteer and capture 50 butterflies; let X denote the number of those that are already tagged. What is the distribution of X? What is the probability that you catch at least one tagged butterfly?
