A collector of antique clocks sold at auction believes that the price received for the clocks may
be modeled as a linear function of the age of the clocks and the number of bidders at the auction.
After a preliminary study and collection of 32 observations, the collector came up with the
following second-order model:
y = BO+B₁x₁+B₂x₂ + ß3 x1x2 +B4x² +ɛ, where y: price of a clock; x₁: age of a clock; x2: the
number of bidders. Considering the output below and by setting a = 0.05, answer the following
questions.
The regression equation is
Price = 262 +2.26 Age + 14.2 Bidder + 1.13 AgeBid 4.20 Bid^2

A real estate analyst believes that the three main factors that influence an apartment's rent in a college town are the number of bedrooms, the number of
bathrooms, and the apartment's square footage. For 40 apartments, she collects data on the rent (y, in $), the number of bedrooms (x1), the number of
bathrooms (x2), and its square footage (x3). She estimates the following model: Rent = Bo + B1 Bedroom + B2 Bath + B3Sqft + ɛ. The
following table shows a portion of the regression results.

In a certain country, total alcoholic beverage sales are reported throughout the year. Sales were reported as $113.8 billion at the beginning of 2002 and $135.5 billion
the beginning of 2004.
(a) Let the x-axis denote time and the y-axis denote the amount of alcohol sales (in billions). Let x = 0 correspond to 2002. Fill in the blanks: The given data is represented by the points (113.8) and (2,
(b) Find the linear equation determined by the two points in part (a).
(c) Use the equation in part (b) to estimate the alcohol sales produced in 2003.

- A real estate analyst believes that the three main factors that influence an apartment's rent in a college town are the number of bedrooms, the number of bathrooms, and the apartment's square footage. For 40 apartments, she collects data on the rent (y, in $), the number of bedrooms (x1), the number of bathrooms (x2), and its square footage (x3). She estimates the following model as Rent = Bo + B1 Bedroom + 82 Bath + 83 Sqft + 2. The following ANOVA table shows a portion of the regression results. df MS Regression 3 5,694,727 1,898,242 50.88 Residual 36 1,343,171 37,310 Total 39 7,037,898 Coefficients Standard Error t-stat p-value Intercept 308 110.0 2.8 0.0010 Bedroom 248 60.8 4.08 0.0007 Bath 92 53.9 1.71 0.1192 Sqft 0.1 0.05 0.0277 The slope coefficient for Bedroom indicates that, holding other explanatory variables constant,arrow_forwardThe graph of a quadratic function f passes through the points (−2, 4), (1, 1) and (5, 0).
