Demand can be estimated with experimental data, time-series
data, or cross-section data. In this case, cross-section data
appear in the Excel file. Soft drink consumption in cans per capita
per year is related to six-pack price, income per capita, and mean
temperature across the 48 contiguous states in the United
States.

Demand can be estimated with experimental data, time-series
data, or cross-section data. In this case, cross-section data
appear in the Excel file. Soft drink consumption in cans per capita
per year is related to six-pack price, income per capita, and mean
temperature across the 48 contiguous states in the United
States.
Given the data, please construct the demand estimation for soft
drink consumption in the United States by
(1) a multiple-linear regression equation, and
(2) a log-linear (exponential) regression equation...

Results obtained from a tension test on a bar of uniform cross
section 10 mm x 10 mm subjected to an axial pull of 8000 N were
tabulated. The lateral dimensions of the bar were found to be
changed to 9.9985 mm x 9.9985 mm while using a material having
modulus of rigidity equal to 0.8 x 107 N/cm2. By determining the
values for different moduli, identify the properties of material
and establish the relationship between them. What changes...

Derive below Results 1 to 4 from Axioms 1 to 3 given in Section
2.1.2 in the textbook.
Result 1: P(Ac)=1−P(A)
Result 2 : For any two events A and B, P (A∪B) = P (A)+P (B)−P
(A∩B)
Result 3: For any two events A and B, P(A) = P(A ∩ B) + P(A ∩
Bc)
Result 4: If B ⊂ A, then A ∩ B = B. Therefore, P(A) − P(B) = P(A
∩ Bc), and
P(A) ≥ P(B).
