Nesta is making a scatterplot of the digit spans (how many numbers you can remember and repeat back) for his psychology class, with the spans for digits the students hear on one axis and the span for digits the students read on the other. The association is strong, but he notices that one student has a visual digit span that is twice as long as anyone else. What statistical validity question is he raising?Is the correlation statistically significant?

Is there a restriction of range?

Is the relationship curvilinear?

Could outliers be affecting the relationship?

Answers

Answer 1
Answer:

Answer:

Could outliers be affecting the relationship?

Explanation:

In most practical circumstances an influence outlier decreases the value of a correlation coefficient and weakens the regression relationship, but it's also possible that in some circumstances an outlier may increase a correlation value and improve regression.

Notice that in the scenario it is mentioned that ''he notices that one student has a visual digit span that is twice as long as anyone else.'' , this will raise the question as to ''what is increasing the value of the correlation coefficient  (the span) between the 'digits the students hear' AND 'the digits the student read'

Which phrase defines a demand schedule?A.)a chart showing the impact of demographic changes on demand
B.)a table showing the quantity demanded for a good at different prices
C.)a graph tracking the increase in demand at decreasing prices
D.)a report analyzing factors causing a change in demand for goods

Answers

The correct answer is B, a table showing the quantity demanded for a good at different prices. The demand schedule shows how many people want a specific product depending on its price. For example, if a price decreases, the demand schedule will likely show an increase in quantity demanded, because more people will want something that's cheaper. It doesn't concern demographic changes on demand (which has more to do with the population than the individual), it's not a graph (but instead a table), and it's not an analytical report that shows why a change in goods is happening (instead it just shows the change itself).
The question says, which phrase defines a demand schedule. The correct option is B. A demand schedule is a table which show the quantity of goods demanded by consumers at different price level. The quantity that will be demanded can be calculated using this table if the price level is given. The demand curve is usually drawn from the demand schedule.

Market failure occurs when a free market is unable toa. distribute resources efficiently.
b. provide open opportunity
c. meet government regulations.
d. encourage innovation

Answers

The market failures can result in overproduction, underproduction, misallocation of resources, and negative externalities (such as pollution) address these failures and promote economic efficiency and societal well-being, governments may intervene through policies and regulations, such as taxes, subsidies, antitrust laws, and public provision of certain goods and services.

**Market failure occurs when a free market is unable to:**

**a. distribute resources efficiently.**

Explanation:

Market failure refers to a situation in which the free market system, left to its own devices without government intervention, fails to allocate resources efficiently.

Here's a breakdown of the options:

- **a. Distribute resources efficiently:** This is the correct statement. Market failure occurs when resources, such as goods and services, are not allocated in a way that maximizes societal welfare or efficiency.

Examples of market failure include externalities (positive or negative), public goods, information asymmetry, and monopolies, all of which can lead to inefficient resource allocation.

- **b. Provide open opportunity:** While providing open opportunity is an important aspect of a free market system, market failure is specifically related to inefficiencies in resource allocation, not necessarily a lack of opportunity.

- **c. Meet government regulations:** Market failure can occur in the presence of government regulations or in their absence.

Government regulations are often put in place to address market failures or prevent them, but market failures can still occur despite regulations.

- **d. Encourage innovation:** The role of market failure is not directly related to innovation.

However, innovation can be influenced by market conditions, and market failures may hinder or distort incentives for innovation.
