Nancy is a graduate student studying health economics. She proposed that the proportion of expenses on healthcare for people that exercised every day was less than 10% of the national average. To test this, she conducts a hypothesis test, at a 10% significance level, and randomly samples people that exercised every day. Working through the testing procedure, she calculated the following: • The test statistic for this hypothesis test is 1.98. • The critical value for this hypothesis test is 20.1 = 1.282. Based on this context and the null and alternative hypothesis, what type of hypothesis test should be used? Use the blue dot in the graph below to select the appropriate test and then plot the critical value on the x-axis.
Answers
Nancy should use a one-tailed hypothesis test to test whether the proportion of expenses on healthcare for people who exercise every day is less than 10% of the national average.
Here's a step-by-step explanation:
Null Hypothesis (H0): The proportion of expenses on healthcare for people who exercise every day is greater than or equal to 10% of the national average.
Alternative Hypothesis (H1): The proportion of expenses on healthcare for people who exercise every day is less than 10% of the national average.
Significance Level (α): Nancy sets a significance level of 0.10, which indicates that she is willing to accept a 10% chance of making a Type I error (rejecting the null hypothesis when it is true).
Test Statistic: Nancy calculates the test statistic for her sample, which is 1.98.
Critical Value: The critical value is determined based on the chosen significance level and the distribution of the test statistic. In this case, the critical value is 1.282.
One-Tailed Test: Nancy uses a one-tailed test because she is specifically interested in whether the proportion of expenses on healthcare for people who exercise every day is less than 10% of the national average.
Rejection Region: Since the critical value of 1.282 falls to the left of the mean on the standard normal distribution, Nancy should shade the area to the left of 1.282 as the rejection region.
Test Decision: Nancy compares her test statistic of 1.98 with the critical value. Since 1.98 falls in the rejection region, she rejects the null hypothesis.
Conclusion: Based on the hypothesis test results, Nancy can conclude that the proportion of expenses on healthcare for people who exercise every day is indeed less than 10% of the national average.
In summary, Nancy uses a one-tailed hypothesis test, compares the test statistic with the critical value, and makes a decision to reject the null hypothesis, indicating that the proportion of expenses on healthcare for people who exercise every day is less than 10% of the national average.

Disadvantages of choosing a job that is extremely popular or in demand
Answers
The disadvantage of choosing a job that is very popular or a job that is in high demand is that after a while such a job may become saturated or it would become monotonous.
What is a high demand job?This is the term that is used to refer to a job that the people that wpould employ labor are constantly in need of. Such a job is one that would require the people that have the qualification to opt in and get the places and the roles that they are to fill.
The issues that may arise from such a job that is in high demand is that after a period, such a job may have a lot of persons that would want to fulfil the role.
The number of qualified persons may become more than the job that is available for the people to do in the long run.
Hence this is a disadvantage. Therefore I would conclude by saying that the disadvantage of choosing a highly popular job is that the number of persons that are willing to fulfil the role may exceed the job overtime.

The concept of limited liability
Answers
Answer: Function, The function of the concept of limited liability is to provide the owners of businesses a way to protect their personal assets. For example, if a business is sued, the person seeking compensation cannot go after the personal property of the business' owners.
Types The concept of limited liability gives rise to a variety of different types of business organizations.These include corporations and limited liability companies, all of which are created by the laws of each of the 50 states.
Significance The concept of limited liability plays a significant role in commerce. Absent the concept of limited liability, individuals would shy away from investing in businesses of any type. The vast majority of individuals would not want to put their personal property at risk by becoming involved in a business enterprise.
Features The concept of limited liability restricts the amount of money a person risks to what she invests in a business enterprise
Exception Protections normally associated with the concept of limited liability can be set aside in certain situations. For example, if a business owner co-mingles personal and business assets -- in a common bank account, for example -- an individual with a claim against the business likely can seek compensation from some, if not all, of the business owner's personal assets.
Expert Assistance A business owner facing a situation in which another individual or business makes a claim against the business should seek legal assistance. A qualified attorney not only protects the interests of the business but works to ensure that the owner's personal assets do not end up in jeopardy.

what is the effective annual rate for a stated rate of 12%, compounded quarterly? report your answer in decimal form rounded to the fourth decimal place.
Answers
The effective annual rate for a stated rate of 12%, compounded quarterly is 12.5508% (0.1255 in decimal form), rounded to the fourth decimal place
To calculate the effective annual rate (EAR) for a stated rate of 12% compounded quarterly, you'll need to use the following formula:
EAR = (1 + i/n)^(n*t) - 1
Where i is the stated annual interest rate (as a decimal), n is the number of compounding periods per year, and t is the number of years.
In this case, i = 0.12 (12%), n = 4 (compounded quarterly), and t = 1 (as we're looking for the annual rate).
Now, plug the values into the formula:
EAR = (1 + 0.12/4)^(4*1) - 1
EAR = (1 + 0.03)^4 - 1
EAR = (1.03)^4 - 1
EAR ≈ 1.1255 - 1
EAR ≈ 0.1255
So, the effective annual rate is approximately 0.1255 or 12.55% when rounded to the fourth decimal place.

which of the following will result in the short run if the government imposes a binding quota? responses a decrease in the price paid by consumers a decrease in the price paid by consumers a rightward shift in the supply curve a rightward shift in the supply curve a leftward shift in the demand curve a leftward shift in the demand curve an increase in consumer surplus an increase in consumer surplus a deadweight loss
Answers
If the government imposes a binding quota, a decrease in consumer surplus and a deadweight loss are likely to result in the short run.
When a binding quota is imposed, it restricts the quantity of a good that can be produced or consumed. As a result, the available supply decreases, leading to a decrease in consumer surplus. Consumers are willing to pay a certain price for the good, but due to the restricted supply, they may have to pay higher prices or face limited availability.
Additionally, the imposition of a binding quota creates a deadweight loss. Deadweight loss occurs when the allocation of resources is inefficient, leading to a loss in overall economic welfare. In this case, the binding quota disrupts the natural supply and demand equilibrium, causing some potential gains from trade to be lost, resulting in deadweight loss.
Therefore, in the short run, the government-imposed binding quota is likely to lead to a decrease in consumer surplus and the presence of a deadweight loss.

D.
The room price is left-skewed because the mean is greater than the median.
E.The room price is
right-skewed
because the mean is
greater than
the median
Answers
The room price is right-skewed based on the information provided because the mean is greater than the median.
To determine whether the room price is symmetric, left-skewed, or right-skewed, we need to compare the mean and median. In a symmetric distribution, the mean and median are equal.
In a left-skewed distribution, the mean is less than the median, while in a right-skewed distribution, the mean is greater than the median.
In this case, the question states that "the mean is less than the median." According to option (C), this would suggest that the room price is right-skewed. However, this contradicts the information provided in the question, which states that "the mean is equal to the median."
Therefore, option (C) can be ruled out.
Option (D) states that the room price is left-skewed because the mean is greater than the median. Since this contradicts the given information, it can also be eliminated.
This leaves us with option (E), which states that the room price is right-skewed because the mean is greater than the median.
Since this option aligns with the information provided, it can be concluded that the room price is indeed right-skewed.

Cash received prior to delivering a product or performing a service is called a(n) a.unearned asset. b.unearned revenue. c.unearned expense. d.unearned contra-asset.
Answers
The correct answer is b. unearned revenue.
Unearned revenue, also known as deferred revenue or advance payments, refers to the cash a company receives from its customers for goods or services that it has not yet delivered or performed. Unearned revenue is considered a liability on the company's balance sheet until the work is completed or the product is delivered, at which point it becomes revenue that can be recognized on the income statement.
Unearned revenue is commonly found in industries such as software and subscription-based services, where customers pay upfront for future access to products or services. It's essential for companies to properly account for unearned revenue to avoid overstating their revenue and profits in a given period.
When a company receives unearned revenue, it records it as a liability on its balance sheet and recognizes it as revenue on the income statement when the associated goods or services are provided. The amount of unearned revenue decreases over time as the company fulfills its obligations to its customers.
In summary, unearned revenue represents cash received by a company before it delivers a product or service to its customers, making it a liability on the company's balance sheet until the related revenue is recognized on the income statement.

Answers
A company that issued 5,000 zero-coupon bonds with face value of $1,000 at a price of $734 each. The company borrowed $3,670,000 in this bond offering.
The company borrowed $3,670,000 in this bond offering because the bonds were sold at a discount of $266 each, meaning the total amount received from the sale of the 5,000 bonds was $3,670,000.
The face value of the bonds was $1,000 each.
Number of zero coupon bonds issued = 5,000
Issue price per zero coupon bond = $734
Total borrowed amount = 5,000 × 734 = 3,670,000
So the company was able to borrow $3,670,000 without paying interest on the loan.
