Consider the natural log transformation (“ln” transformation) of variables labour cost (L_COST), and total number of rooms per hotel (Total_Rooms). 4.1 Use the least squares method to estimate the regression coefficients b0 and b1 for the log-linear model 4.2 State the regression equation 4.3 Give the interpretation of the regression coefficient b1. 4.4 Give an interpretation of the coefficient of determination R2 . Also, test the significance of your model using the F-test. How, does the value of the coefficient of determination affect the outcome of the above test? 4.5 Test whether a 1% increase of the total number of rooms per hotel can increase the labour cost by more than 0.20%? Use the 5% level of significance for this test.

Consider a spherical capacitor
made of the 3 linear dielectrics: 1 for a < r < b, 2 for b
< r < c, and 3 for c < r < d. There
is conducting material covering the inner surface (r=a) and the
outer surface (r=d). What is
the capacitance of this device? You can assume that there is total
charge Q and -Q built up on
each of the inner and outer conducting surfaces and that there is a
potential di erence V between
the conductors.

Respond to the following statement: World War II fundamentally changed the way that Europeans understood themselves. In the second half of the 20th century, the experience of the war led people on both sides of the Iron Curtain before 1989, and throughout Europe after, to redefine what it meant to be European. By the end of the century, nations throughout the continent built an identity on a vision of unity and tolerance of everyone living in Europe. Support, refute, or refine this statement.

Problem 3: A single phase 60 Hz two-winding power transformer is
rated at 2400V/240V and 100 kVA with
Zeq = 0.5 + j0.8 Ohm. If an autotransformer is built from this
conventional transformer to supply a load at
2640V with supply voltage 2400V. Draw the autotransformer and
calculate Zeq, the voltage, current and
apparent power rating of the auto transformer. Also calculate the
apparent power rating advantage of
autotransformer over conventional transformer.

You want to buy a new house. Your options are a tradition house
for $350,000 and a 3D printed concrete
house for $100,000. These houses are built over a plot that
increases 5% every year. You want to
keep this house for 20 years and make a bit of money at the
end.
Which house would be the better option if both homes lose 2% of
its value, but also increase due to an
inflation of 3.22% every year?
