The size of the sample that must be used is 264. The correct sample size is 264. Read below about how to arrive at the sample size.
<h3>What is the sample size that must be used?</h3>
p′ = x / n where x represents the number of successes and n represents the sample size. The variable p′ is the sample proportion and serves as the point estimate for the true population proportion.
Then, it follows that,
p= 30/10 x 88 = 264
Therefore, the correct answer is 264.

Answer:
1. 20 units
2. $600
Explanation:
1. 
MC = 4q
Price, P = $80
For maximizing profits,
Marginal cost = Price of the commodity
4q = 80
q = 20 units
= 200 + 800
= 1,000
2. Profit = Total revenue - Total cost
= (Price × Quantity) - TC
= (80 × 20) - $1,000
= $1,600 - $1,000
= $600
3. We know that the firm in the short run will be produce at a point where total revenue is greater than the total variable cost
Average variable cost = variable cost ÷ quantity
= 2Q
MC = 4Q
Here, MC is greater than AVC at any given point.
so in the short run firm will producing short run positive profit.
Answer:
Mary should answer that more than half of the boxes not be rejected.
Explanation:
Probability:
Box has one defective screen = 0.6
Box has three defective screen = 0.4
no. of screens in a box = 8
The box is rejected if both of the inspected screens are defective.
Probability of rejecting a box:
= 0.04286
Only 4.286% of the boxes will be rejected.
Therefore, Mary should answer that more than half of the boxes not be rejected.
The repeating economic changes that happen in a society over time are known as business cycles.
Business cycles are one sort of fluctuation that can be seen in a country's overall economic activity, a pattern of booms that occur roughly at the same time in various economic activities, followed by contractions that are equally widespread.
The repeating economic changes that happen in a society over time are known as business cycles. It can be recognized by changes in the GDP and other macroeconomic indicators.
Business cycles are made up of coordinated cyclical upswings and downswings in output, employment, income, and sales, which are four broad indices of economic activity.
Expansions and contractions, commonly known as recessions, are the two contrasting phases of the business cycle.

Answer:
total equivalent units for materials = 6,310
Explanation:
700 units in beginning work in process:
- materials: 70% complete, $8,700, completed 490 equivalent units, not completed 210 units
- conversion: 10% complete, $3,700
units started in to production 6,400
units transferred out 5,600
ending work in process 1,500
- materials: 80% complete, completed 1,200 equivalent units for materials
- conversion: 25% complete
materials added $92,200
conversion costs added $269,600
equivalent units for materials:
- beginning WIP equivalent units to be completed = 210
- units started and completed = 5,600 - 700 = 4,900
- ending WIP = 1,200 equivalent units
- total equivalent units for materials = 6,310
