99.7 percentage of the data lies between 140 and 212 pounds when the distribution of the standard deviation is normal.

<h3>What is standard deviation?</h3>

Any given quantity, which is used to express that how many observations  differ from others in the total observations of a data, is referred to as standard deviation. It is represented by σ.

To calculate the percentage of data lying between the given values, we will use the formula of empirical method and the given information to compute as under,

\rm P(mu-3\ x\ \sigma < X < \mu + 3\ x\ \sigma)

Solving further,

\rm P(176-3\ x\ \12 < X < \176+ 3\ x\  12) = 0.997

Hence, the significance upon the standard deviation of data weighted by Naomi is as aforementioned.

In Chile, one worker can harvest 4 pounds of peppers or 4 pounds of coffee beans. In Argentina, one worker can harvest 2 pounds
Monica [59]

Chile- 4 pounds of coffee beans, Argentina - 16 pounds of coffee beans, is the correct solution of the question.

<h3>Explanation of the question?</h3>

It loses 4 pounds of coffee beans if one worker produces 4 pounds of peppers. As a result, if the worker produces 4 pounds extra peppers, 4 pounds of coffee beans will be lost. As a result, the opportunity cost of generating an additional 4 pounds of peppers for Chile is equal to 4 pounds of coffee beans.

Argentina's case:

It loses 8 pounds of coffee beans if one worker produces 2 pounds of peppers.

As a result, if the worker produces 1 pound of pepper, it loses = 8/2 = 4 pounds of coffee beans.

The worker will lose = 4 * 4 = 16 pounds of coffee beans if he produces 4 pounds of peppers.

As a result, the potential cost of producing an additional 4 pounds of peppers for Argentina is 16 pounds of coffee beans.

Thus, it is 4 pounds of coffee beans, Argentina - 16 pounds of coffee beans.

You and your college roommate eat three packages of Ramen noodles each week. After graduation last month, both of you were hired
inn [45]

Answer:

The answer to this question is b. Yours will be positive and your roommate's would be negative.

Explanation:

Income elasticity of demand is the degree of responsiveness of demand to changes in income. In other words, it measures how changes in income of consumers will affect the quantity of commodities demanded by such consumers.

An income elasticity of demand can be positive or negative.

It is positive, when an increase in income leads to an increase in the quantity demanded by the customer. However it is referred to as negative when an increase in income leads to decrease in the quantity demanded by the consumer.    

In  the question above, it can be seen that the increase in income of the first person brought about increase in the commodity demanded thereby making his income elasticity of demand positive. one the other hand, the increase in the income of his roommate, brought about decrease in his demand which translate to the fact that his income elasticity of demand would be negative.

Hence the answer given.

Consider the multifactor APT with two factors. Stock A has an expected return of 17.6%, a beta of 1.45 on factor 1, and a beta o
ehidna [41]

Answer:

The risk premium on factor 2 = 9.26%.

Explanation:

Let us denote the risk premium of factor 2 as x

Below is the formula we can use to calculate the risk premium of factor 2.

Expected return on stock = (Beta (factor 1)* expected return of 1) +(beta of 2x * risk free reate)

17.6% = (1.45*3.2%) + 0.86x+5%

17.6 = 4.64 + 0.86x+5%

17.6 - 4.64 - 5= 0.86x

7.96 = 0.86x

x = 7.96/0.86 =9.2558

The risk premium on factor 2 = 9.26%.
