Scott Bell Builders would like to predict the total number of
labor hours spent framing a house based on the square footage of
the house. The following data were compiled on ten houses recently
built and the resulting regression equation is:
y-hat = 80.8757 +
5.3605x
Sq. Feet (100s)
Framing Hours
Sq. Feet (100s)

The correct interpretation of b1 in the
regression equation is:
Group of answer choices
for each additional 5.3605 square footage, 1 more framing hour
is expected to be needed
for each additional 100 square footage, 5.3605 more framing
hours are expected to be needed
for each additional square foot, 5.3605 more framing hours is
expected to be needed
for each additional 536.05 square footage, 100 more framing
hours are expected to be needed
The correct interpretation of b0 in the
regression equation is:
Group of answer choices
8,087.57 sq. ft. is the largest house that can be predicted
80.8757 square feet is expected to be framed per hour
8,087.57 hours is the minimum expected time needed frame a
10,000 sq. ft. house
a house with zero square feet is expected to require 80.8757
framing hours
For a 2,500 sq. ft. house,
Group of answer choices
the number of framing hours is expected to be 134.4757
the number of framing hours required is expected to be
214.8882
the number of framing hours is expected to be 536.05
the number of framing hours required is expected to be
8,087.57
