A realtor is analyzing the relationship between the sale price of a house (Price in $), its square footage (Sqft), the number of bedrooms (Beds), the number of bathrooms (Baths), and a Colonial dummy variable (Colonial equals 1 if a colonial-style house, 0 otherwise). The accompanying data file shows information on 36 recent sales.

a. Estimate Price = β₀ + β₁Sqft + β₂Beds + β₃Baths + β₄Colonial + ε. Show the regression results in a well-formatted table.

b. At the 5% significance level, are the predictor variables jointly significant in explaining Price?

c. At the 5% significance level, are all predictor variables individually significant in explaining Price?
