Let x be per capita income in thousands of dollars. Let y be the number of medical doctors per 10,000 residents. Six small citie

MAVERICK [17]

Answer:

The percentage of variation esplained by the model is given by the determination coefficient, on this case:

$R^2 = 0.934^2 =0.872$

And we have 87.2% of the variation explained by the linear model given.

$\hat y = 5.756(8.5) -36.895=12.031$

And we have 12.031 doctors per 10000 residents.

Explanation:

Assuming the following dataset:

x y

8.6 9.6

9.3 18.5

10.1 20.9

8.0 10.2

8.3 11.4

8.7 13.1

Assuming this question: "The data has a correlation coefficient of r = 0.934. Calculate the regression line for this data. What percentage ofvariation is explained by the regression line? Predict the number of doctors per 10,000 residents in a town with a per capita income of $8500."

We want a linear model like this:

$y = mx +b$

Where m represent the slope and b the intercept for the linear model. And we cna find the slope and b with the following formulas:

$m = \frac{n \sum xy - \sum x \sum y}{n \sum x^2 -(\sum x)^2}$

$b = \frac{\sum y}{n} -m \frac{\sum x}{n}$

And from the dataset we have the following values:

$n= 6, \sum x =53, \sum y = 83.7 , \sum xy = 755.89, \sum x^2 = 471.04$

And replacing into the equation for m we got:

$m =\frac{6(755.89) - (53)(83.7)}{6(471.04) -(53)^2}=5.756$

And the intercept:

$b = \frac{83.7}{6}-36.895 5.756 \frac{53}{6}=-36.895$

And then the linear model is given by:

$\hat y = 5.756 x -36.895$

We can find the estimation replacing x = 8.5 into the linear model and we got:

$\hat y = 5.756(8.5) -36.895=12.031$

And we have 12.031 doctors per 10000 residents.

The percentage of variation esplained by the model is given by the determination coefficient, on this case:

$R^2 = 0.934^2 =0.872$

And we have 87.2% of the variation explained by the linear model given.

Suppose an economist advises a city's mayor to begin charging drivers a fee to drive on a busy highway during congested times. T

Kazeer [188]

Answer:

The correct answer is the letter b. This is a common occurrence. The policymaker usually disregards an economist's advice because they do not believe it is the most efficient policy.

Explanation:

It is common for policymakers to disregard the advice of an economist. This is because in addition to their often finding that the policies suggested by economists are not the most efficient, they observe the political return of such action, ie not just efficiency, but the extent to which this policy will bring political benefits. Thus, as in this case, the policy is not implemented because it is not popular with voters.

Consider the market for natural gas. In this industry, low average costs are obtained only through large-scale production. In ot

Serjik [45]

Answer:

A) Economies of scale

Explanation:

Producing natural gas is very expensive and requires a large investment. The costs and risks of the processes involved in the upstream and downstream of natural gas discourage competition. Besides requiring a large initial investment, a drilling company can never be 100% sure that they will be able to find and extract natural gas or petroleum. So besides having to spend a lot of money, you are assuming a great risk.

Even if a competitor finds natural gas, in order for the downstream process to be profitable, they must be able to extract a large volume to achieve economies of scale.
