Answer:
The store manager is 95% confident that the average amount spent by all customers is between $ 31.84 and $ 38.66.
Explanation:
In statistics, a confidence interval is the probability that the parameter of a population lies between two set of values when a random sample of the population is drawn for a specific percentage of times. This means that the confidence interval is formed about the whole population not the sample from which it is calculated.
The probabilities of a confidence interval can take any number, but 95% and 99% confidence level that are usually used.
It should be noted that, for example, 95% confidence level implies that there is a 95% chance that the true mean of the population lies within the calculated confidence interval.
Therefore, the statement which gives a valid interpretation of the interval in the question is the first one which states that "the store manager is 95% confident that the average amount spent by all customers is between $ 31.84 and $ 38.66."
I wish you the best.
Answer: -0.5
Explanation:
Based on the information given, the price elasticity of demand will be calculated as follows:
= dQ/dP × P/Q
where,
dQ/dP = -1
P = 100
Q = 200 – P + 25 U – 50 P beer
Q = 200 - 100 + 25(8) - 50(2)
Q = 200 - 100 + 200 - 100
Q = 200
Therefore, dQ/dP × P/Q
= -1 × (100/200)
= -1 × 1/2
= -1 × 0.5
= -0.5
The price elasticity of demand is -0.5.
It includes the combination of the various institutions, agencies, entities, decision-making processes, and patterns of consumption that comprise the economic structure of a given community. As such, an economic system is a type of social system....
Answer: Individual demand refers to the demand for a good or a service by an individual (or a household). Individual demand comes from the interaction of an individual's desires. Where as an aggregate demand is an economic measurement of the total amount of demand for all finished goods and services produced in an economy. Aggregate demand is expressed as the total amount of money exchanged for those goods and services at a specific price level and point in time.

Answer:
Instructions are listed below
Explanation:
We don't have enough information to answer the question numerically. But, I can provide a few formulas of how to answer it.
A)
Revenue/Sales (+)
Cost of Goods Sold (COGS) (-)
=Gross Profit
Marketing, Advertising, and Promotion Expenses (-)
General and Administrative (G&A) Expenses (-)
=Net operating income
B)Break-even point (dollars) fixed costs/ contribution margin ratio
Contribution margin ratio= (Price - unitary variable cost)/Price
1) Increase in Unitary variable cost:
Contribution margin= price - new unitary variable cost
2) Variance in income= new sales* contribution margin - increase in fixed costs
3) Prepare the income statement again
C) Break-even point= fixed costs/ contribution margin
