To conduct a preelection opinion poll on a proposed amendment to the state constitution, a random sample of 10 telephone prefixes (first three digits of the phone number) was selected, and all households from the phone prefixes selected were called "cluster sample".
<u>Explanation:</u>
A selection method which is applied in statistical populations where socially unified but internally diverse categories are obvious, understood as cluster screening. It is also used in studies into marketing. The total population is separated into those groups in this sampling program and a simple random selection of the groups is chosen.
For an instance, in a class of total strength, one need to analyse the interest of students for science and arts individually, so the group is divided accordingly in class, after separation the quality of knowledge art and science student carry is tested by simple random selection from such divisions.
Answer: Supply of T-shirts decreasing
Explanation:
If the supply of T-shirts decreases, the equilibrium quantity of t-shirts being supplied to the market will decrease as well. Assuming that demand stays the same, the leftward shift of the supply curve will intersect with the demand curve at a higher equilibrium price.
This is simply because as the t-shirts are in short supply, people will be willing to pay more to have them as they are not as widespread as before.
Answer: Incremental
Explanation: Also called differential cost
Answer:
$27,250
Explanation:
The computation of incremental income or loss on reworking the units is shown below:-
For computing the incremental income or loss on reworking the units first we need to follow some steps which is shown below:-
Incremental revenue per unit = Selling price after rework - Selling price as scrap
= $22.00 - $5.60
= $16.40
Total Incremental Revenue = Incremental revenue per unit × Total defective units
= $16.40 × 2,500
= $41,000
Total rework costs = Total defective units × Defects per unit
= 2,500 × $5.50
= $13,750
Now,
Incremental income or loss on reworking the units = Total Incremental Revenue - Total rework costs
= $41,000 - $13,750
= $27,250
