There are numerous variables that are believed to be predictors of housing prices, including living area (square feet), number of bedrooms, number of bathrooms, and age. The information in the MBA 6300 Case Study.xlsx file pertains to a random sample of houses located in the greater Wilmington, Delaware area.
1. Develop a simple linear regression model to predict the price of a house based upon the living area (square feet) using a 95% level of confidence.
a. Write the reqression equation
b. Discuss the statistical significance of the model as a whole using the appropriate regression statistic at a 95% level of confidence.
c. Discuss the statistical significance of the coefficient for the independent variable using the appropriate regression statistic at a 95% level of confidence.
d. Interpret the coefficient for the independent variable.
e. What percentage of the observed variation in housing prices is explained by the model?
f. Predict the value of a house with 3,000 square feet of living area.
2. Develop a simple linear regression model to predict the price of a house based upon the number of bedrooms using a 95% level of confidence.
a. Write the reqression equation
b. Discuss the statistical significance of the model as a whole using the appropriate regression statistic at a 95% level of confidence.
c. Discuss the statistical significance of the coefficient for the independent variable using the appropriate regression statistic at a 95% level of confidence.
d. Interpret the coefficient for the independent variable.
e. What percentage of the observed variation in housing prices is explained by the model?
f. Predict the value of a house with 3 bedrooms.
3. Develop a simple linear regression model to predict the price of a house based upon the number of bathrooms using a 95% level of confidence.
a. Write the reqression equation
b. Discuss the statistical significance of the model as a whole using the appropriate regression statistic at a 95% level of confidence.
c. Discuss the statistical significance of the coefficient for the independent variable using the appropriate regression statistic at a 95% level of confidence.
