A manufacturer of computer workstations gathered average monthly sales figures from its 56 branch…
Q = 15,000 - 2.8 P + 150 A + 0.3 Ppc + 0.35 Pm + 0.2 Pc
(4234) (1.29) (175) (0.12) (0.17) (0.13)
R^2 = 0.68 F= 21.25
The unsteadys and their estimated computes are:
Q = Quantity
P = Expense of the basket = $7000
A = Advertising expenditures = $52000
Ppc = Middle expense of identical computer = $4000
Pm = Middle expense of minicomputer = $15,000
Pc = Middle expense of a necessary competitor's workstation = $8,000
( ) the enumerate in brackets is the touchstone fault of class SEE
The t-touchstone is = coefficient of unsteady/SEE
a. Compute the elasticity of each unsteady.
b. What would betide to Quantity if expense (P) increased by $500
c. What would betide to Quantity if middle expense of identical computer decreases by $1000.
d. Conduct a t-touchstone for the statistical reason of each unsteady. Which ones are suggestive at 5% raze of reason.
e. What does the compute of R^2 balance for this touchstone.
