Question

You must use Excel to perform the regression analysis. Provide the answers under the space provided for each question. You must provide the Excel output for the question along with the answers. Round off the values on the output to three-five decimal places if appropriate.

Questions:

  1. As preliminary analysis the dataset includes information on 50 homes currently for sale, but some homes have unusually high prices, square footage, and lot sizes. To refine the dataset for analysis, apply the following exclusion criteria:
  • Exclude any home with a price greater than $1,000,000.
  • Exclude any home with square footage (SqFt) greater than 3000 ft².
  • Exclude any home with a lot size greater than 10,000 ft².

After performing these exclusions, how many homes remain in the dataset?

Show the observations that excluded (2p)

  1. How many categorical variables are present in the dataset? How will you incorporate these categorical variables into the regression analysis? (2p)

Create indicator (dummy) variables for each categorical variable to identify each categorical variable and convert into a binary variable (0 or 1). Here’s a guide based on categorical variables: (3p)
