A simple random sample of 30 items resulted in a sample mean of 25. The population standard deviation is ? = 5' Round your answers to two decimal places a. what is the standard error of the mean,05? b, At 95% confidence, what is the margin of error?
Answers
a. The standard error of the mean is 0.91.
b. At 95% confidence, the margin of error is 1.86.
a. A simple random sample of 30 items resulted in a sample mean of 25. The population standard deviation is σ = 5.
Standard Error of Mean(SEM) = σ/√n
Where,σ = population standard deviation
n = sample size
SEM = 5/√30 = 0.91
b. Margin of Error = Critical value * Standard Error of Mean
The level of confidence is 95%, therefore the alpha level of 5% is divided equally among the two tails.
α/2 = 0.05/2 = 0.025
Level of Significance (α) = 0.05 or 5%
The degrees of freedom (df) is (n - 1) = (30 - 1) = 29
Using t-distribution table with α = 0.025 and df = 29, the critical value is 2.045
Margin of Error = 2.045 * 0.91 = 1.86
Rounded to two decimal places, the standard error of the mean is 0.91 and the margin of error at 95% confidence is 1.86.

Paid-in capital in excess of stated value would appear on a balance sheet under the category
a. capital stock.
b. retained earnings.
c. additional paid-in capital.
d. contra to stockholders' equity.
Answers
The correct category on a balance sheet for paid-in capital in excess of stated value is "additional paid-in capital." This categorization indicates the amount of capital contributed by shareholders that exceeds the nominal or stated value of the stock.
Paid-in capital in excess of stated value represents the additional amount of money that investors have paid for shares of stock above its par value. Par value is the minimum price assigned to each share of stock by the company at the time of issuance. When investors pay more than the par value for the stock, the excess amount is considered paid-in capital in excess of stated value.
Including paid-in capital in excess of stated value in the "additional paid-in capital" category on the balance sheet allows for a clear representation of the total amount of capital contributed by shareholders, both at par value and the excess amount. This information is important for analyzing the financial health of the company and understanding the level of shareholder investment in the business. This reflects the amount of capital contributed by shareholders above the nominal value of the stock and provides valuable information about the shareholders' equity in the company.

The Hull Petroleum Company and Inverted V are retail gasoline franchises that compete in a local market to sell gasoline to consumers. Hull and Inverted V are located across the street from each other and can observe the prices posted on each other's marquees. Demand for gasoline in this market is Q= 80-12 and both franchises obtain gasoline from their supplier at $410 per gallon. On the day that both franchises opened for business, each owner was observed changing the price of gasoline advertised on its marquee more than 10 times: the owner of Hull lowered its price to slightly undercut Inverted V's price, and the owner of Inverted V lowered its advertised price to beat Hull's price. Since then, prices appear to have stabilized. Under current conditions, how many gallons of gasoline are sold in the market, and at what price? Instructions: Enter your responses rounded to the nearest two decimal places Gallons sold: Price: $
Answers
Answer:
I believe that the demand equation is incomplete, since there is no price (P).
If we just solve this equation like it is, the quantity demanded = 80 - 12 = 68 gallons
if we add the price into the equation:
Q = 80 - 12P
since this is a competitive market, in order to maximize profits, marginal revenue = marginal cost = $4.10 per gallon (not $410).
That means that both companies will sell gasoline at $4.10 per gallon
equilibrium quantity = 80 - (12 x 4.10) = 30.8 gallons of gasoline

A large retailer obtains merchandise under the credit terms of 1/10, net 40, but routinely takes 50 days to pay its bills. (Because the retailer is an important customer, suppliers allow the firm to stretch its credit terms.) What is the retailer's effective cost of trade credit? Assume a 365-day year. Do not round intermediate calculations. Round your answer to two decimal places.
Answers
If a large retailer obtains merchandise under the credit terms of 1/10, net 40, but routinely takes 50 days to pay its bills. The retailer's effective cost of trade credit assuming a 365-day year is 9.60%.
Effective Cost of Trade CreditUsing this formula
Effective Cost of Trade Credit = {1+(D/100-D)}^ (365 / Days after Discount Period) -1
Let plug in the formula
Effective Cost of Trade Credit = [1 + ( 0.01 /0.99 ) ] ^[ 365 / (50−10)]−1
Effective Cost of Trade Credit = [1 + ( 0.01 /0.99 ) ] ^[ 365 / (40)]−1
Effective Cost of Trade Credit =1.096046171−1
Effective Cost of Trade Credit = 096046171 × 100
Effective Cost of Trade Credit = 9.60%
Therefore the 9.60% is the effective Cost of Trade Credit.

As a salesperson would you encourage your existing customers to complain? Why or why not? (100 words minimum)
Answers
As a salesperson, it would not be ideal to encourage existing customers to complain. This is because complaints are generally seen as negative feedback which can potentially harm the reputation of a business.
However, it is important to acknowledge that customers who complain are actually providing feedback that can be used to improve the quality of service or product offered by the business. In this sense, complaints can be viewed as opportunities for improvement.
When handling customer complaints, the salesperson should remain calm and listen carefully to the customer's grievances. They should take the necessary steps to rectify the situation and ensure that the customer is satisfied with the outcome. By doing so, the salesperson can turn a negative experience into a positive one and potentially retain the customer's loyalty.

The question is asking which situation is least appropriate for using input measures of capacity.
The least appropriate situation for using input measures of capacity is when the product variety and process divergence are low.
Input measures of capacity focus on the resources used in the production process, such as labor, materials, and equipment. They are useful when there is a significant learning effect, as in situation a, where productivity rates are expected to change. They are also helpful when the product/service mix is changing, as in situation d.
However, in a situation where product variety and process divergence are low, input measures of capacity may not provide the best insights. In such cases, other measures, such as output measures of capacity, may be more appropriate.

An American car company sells 200 vehicles to Germany for a total of $600,000, while

from Germany. What would the effect of this trade deal be on the United States' GDP?
O U. S. GDP decreases because net exports are negative.
O U. S. GDP increases because net exports are negative.
O U. S. GDP increases because net exports are positive.
O U. S. GDP decreases because net exports are positive.
Answers
The effect of this trade deal on the United States GDP would be an increase because net exports are positive.
Net exports refer to the value of a country's exports minus the value of its imports. In this case, the United States is exporting 200 vehicles to Germany, resulting in a total export value of $600,000. At the same time, the United States is importing 100 cars from Germany, with a total import value of $500,000.
To calculate net exports, we subtract the value of imports from the value of exports: Net Exports = Exports - Imports.
The net exports would be $600,000 - $500,000 = $100,000.
When net exports are positive, it means that the value of exports exceeds the value of imports. Positive net exports contribute positively to a country's GDP. GDP, or Gross Domestic Product, measures the total value of goods and services produced within a country's borders. Since the trade deal results in positive net exports, it would lead to an increase in the United States GDP.

Answers
The b. the short-run and long-run Phillips curves right. In the short run, an increase in the growth rate of the money supply leads to an increase in aggregate demand, which results in higher output and lower unemployment.
This leads to a movement down the short-run Phillips curve. However, in the long run, wages and prices adjust to the increase in aggregate demand, leading to an increase in inflation but no change in output or unemployment. This results in a shift of the short-run Phillips curve to the right and a shift of the long-run Phillips curve to the right as well.
An increase in the growth rate of the money supply would lead to a temporary increase in aggregate demand, causing the short-run Phillips curve to shift right. This is due to the expectation that prices will rise as a result of the increased money supply. In the long run, as people's expectations adjust and the economy returns to its natural rate of unemployment, the long-run Phillips curve will also shift right.

what is project a's discounted payback? do not round intermediate calculations. round your answer to four decimal places.
Answers
Discounted Payback Period of Project A can be calculated as Years Before Full Recovery + (Unrecovered Cost at Start of Year / Cash Flow during Year). Hence, the discounted payback period for Project A is 2.5866.
In order to calculate Project A's discounted payback period, the following formula can be used:
Discounted Payback Period = Years Before Full Recovery + (Unrecovered Cost at Start of Year / Cash Flow during Year)
Here, we need to determine the unrecovered cost at the start of year and the cash flow during the year for each year and then calculate the discounted payback period accordingly. The discount rate for Project A is given as 12%.
Year 0: Unrecovered Cost = -2000
Year 1: Cash flow = 800, Present Value = 800/(1+0.12) = 714.29
Year 2: Cash flow = 1100, Present Value = 1100/(1+0.12)^2 = 853.86
Year 3: Cash flow = 1500, Present Value = 1500/(1+0.12)^3 = 1013.14
Year 4: Cash flow = 1900, Present Value = 1900/(1+0.12)^4 = 1202.62
Year 5: Cash flow = 2400, Present Value = 2400/(1+0.12)^5 = 1381.03
The unrecovered cost is fully recovered in Year 2, so the discounted payback period can be calculated as follows:
Discounted Payback Period = 2 + (2000 - 714.29)/(853.86) = 2.5866 (rounded to 4 decimal places)
Therefore, the discounted payback period for Project A is 2.5866.

The cost of ordering tape is $.75, and carrying costs are 36 cents per roll a year. Lead time is 2 days.Use Table1 and Table2.What is the EOQ?
Answers
Answer:
EOQ (Economic Order Quantity) formula is:
EOQ = √[(2DS)/H]
Where D is the annual demand, S is the cost of placing one order, and H is the carrying cost per unit.
First, we need to find the annual demand:
Annual demand = Daily usage x Days open = 18 rolls/day x 355 days/year = 6390 rolls/year
Next, we need to find the cost of placing one order:
Cost of placing one order = $0.75
Finally, we need to find the carrying cost per unit:
Carrying cost per unit = 0.36
Now we can plug in the values into the EOQ formula:
EOQ = √[(2 x 6390 x 0.75)/0.36] = √[10650] = 103.17
Therefore, the EOQ is 103 rolls (rounded up to the nearest whole number).
