a) ( 0.8509718, 0.8890282)
b) ( 0.7255, 0.7745)
Explanation:
(a)
Given that , a = 0.05, Z(0.025) =1.96 (from standard normal table)
So Margin of error = Z × sqrt(p × (1-p)/n) = 1.96 × sqrt(0.87 × (1-0.87) / 1200)
=0.01902816
So 95 % confidence interval is
p+/-E
0.87+/-0.01902816
( 0.8509718, 0.8890282)
(b)
Margin of error = 1.96 × sqrt (0.75 × (1-0.75) / 1200) = 0.0245
So 95% confidence interval is
p+/-E
0.75+/-0.0245
( 0.7255, 0.7745)
Answer:
a. $28
b. $19
c. 800 watches
Explanation:
The equation is
p = D(q) = 28 - 2.25
The equation of the demand would be
P = 28 - 2.25q
a. The price would be
= $28 - 2.25 × 0
= $28 - 0
= $28
b. The price would be
= $28 - 2.25 × 4
= $28 - 9
= $19
The quantity demanded is come in hundreds so we take only 4
c. The quantity woul dbe
$10 = $28 - 2.25q
$10 - $28 = -$2.25q
-$18 = -$2.25q
So q would be
= 800 watches
Answer:
If a company must expand capacity to accept a special order, it is likely that there will be an increase in fixed costs.
Explanation:
The fixed costs are the part of the total costs of production that remain constant during a given reference quantity in a certain period. These include, for example, depreciation of fixed assets or rental or interest expenses. Since fixed costs are incurred regardless of the application quantity (short-term), they cannot be apportioned to the unit costs according to the cause.
In the present case, given that the company must expand its capacity to take the special order, it means that all of its production factors are totally devoted to production, so that in order to produce a greater quantity of goods, the productive factors must be increased, which are part of the fixed production costs that the company has. Therefore, as the costs of production are altered, there will be an increase in fixed costs.
