Here is the solution:
Given:
Monthly rates of return on the shares of a particular common stock are independent of one another and normally distributed with a standard deviation of 2.2.
A sample of 12 months is taken.
To find:
The probability that the sample standard deviation is less than 3.1.
The probability that the sample standard deviation is more than 1.5.
Solution:
The sample standard deviation is a random variable with a chi-square distribution with 11 degrees of freedom.
The probability that the sample standard deviation is less than 3.1 is equal to the probability that the chi-square random variable is less than (3.1)^2 = 9.61.
The probability that the chi-square random variable is less than 9.61 is 0.9953.
The probability that the sample standard deviation is more than 1.5 is equal to the probability that the chi-square random variable is greater than (1.5)^2 = 2.25.
The probability that the chi-square random variable is greater than 2.25 is 0.0668.
Therefore, the probability that the sample standard deviation is less than 3.1 is 0.9953 and the probability that the sample standard deviation is more than 1.5 is 0.0668.

Answer:
The law of supply and demand is the market rule by means of which the supply of goods and the demand for them are interrelated, linked through price: the higher the price of the good, the lower the demand for it, since that it will be more inaccessible for consumers, with which there will be an excess supply; Whereas, if the price of the good falls, the demand for the good increases and its supply will not meet the consumption expectations of consumers.

Is there a sense in which an increase in costs and a decrease in profits have exactly the same effect on market outcomes, that is, exactly the same effect on the symmetric equilibria of the game? Explain your answer.
Answers
a. In the symmetric mixed-strategy equilibrium of the game, whether dropping out at date 0 is more likely if costs (c) increase depends on the specific structure of the game and the strategies chosen by the players.
b. The probability that exactly one firm drops out at date 0 is not directly affected by an increase in costs (c) since this probability depends on the strategies chosen by the players.
a. Without additional information about the game and the players' strategies, it is not possible to determine the effect of cost increases on the likelihood of dropping out at date 0.
b. The probability that exactly one firm drops out at date 0 is not directly affected by an increase in costs (c) since this probability depends on the strategies chosen by the players. However, an increase in costs could potentially change the players' strategies and, as a result, affect the probability of exactly one firm dropping out. On the other hand, the probability that at least one firm drops out at date 0 could be affected by an increase in costs. Higher costs may lead to lower expected profits for the firms, increasing the incentive for at least one firm to drop out. However, the exact impact would depend on the specific details of the game and the players' strategies.
c. An increase in costs (c) does not necessarily make a monopoly more likely. The likelihood of a monopoly depends on various factors, including market structure, entry barriers, demand elasticity, and the behavior of firms. While an increase in costs could potentially affect market outcomes and make it more difficult for firms to compete, it does not guarantee the emergence of a monopoly. Other factors, such as the number of firms, their market power, and potential entry barriers, also play crucial roles in determining market outcomes.

Do not forget to type the % symbol after multiplying your result by 100 to convert to percentage!
Hint: Your answer will NOT have decimal point.
Example: 75%
Answers
To calculate the sales growth, you can use the following formula:
(Sales Revenue Current Year - Sales Revenue Last Year) / Sales Revenue Last Year x 100%
Plugging in the numbers, we get:
($150,000 - $125,000) / $125,000 x 100% = 20%
Therefore, the sales growth is 20%.
Sales Growth = (Sales Revenue Current Year - Sales Revenue Last Year) / Sales Revenue Last Year × 100%
Sales Growth = ($150,000 - $125,000) / $125,000 × 100%
Sales Growth = $25,000 / $125,000 × 100%
Sales Growth = 0.2 × 100%
Sales Growth = 20%

Graded potentials adhere to the all-or-none principle. true / false
Answers
Graded potentials are proportional to the strength of the input signal and can vary in magnitude.
False. Graded potentials do not adhere to the all-or-none principle.
The all-or-none principle is a concept in physiology, neurology, and biology that states the strength of a neural response is consistent and determined by the intensity of the stimulus. According to this principle, an excitable cell will either respond completely or not at all to a stimulus, without any partial response. However, graded potentials, which are changes in the membrane potential of a cell, do not adhere to the all-or-none principle.
Graded potentials exhibit a proportional relationship between the size of the potential and the strength of the input signal. In other words, the larger the input signal, the larger the resulting graded potential. It is important to note that graded potentials can contribute to the generation of action potentials in neurons if they reach a certain threshold level. The decision for an action potential to occur depends on the summation of graded potentials.
Unlike action potentials, graded potentials are not obligated to trigger an action potential. Their occurrence is contingent upon the strength of the input signal. On the other hand, action potentials consistently occur with the same intensity and rely on reaching a specific threshold level. Therefore, graded potentials deviate from the all-or-none principle due to their variable response based on input strength.

a. What was the original annual rate of return needed to reach Prof. ME's goal when he started the fund 2 years ago? b. Now with only $120,000 in the fund and 8 years remaining until his first child starts college, what APR would the fund have to earn to reach Prof. ME's $440,000 goal if he adds nothing to the account? c. Shocked by his experience of the past 2 years, Prof. ME feels the college mutual fund has invested too much in stocks. He wants a low-risk fund in order to ensure he has the necessary $440,000 in 8 years, and he is willing to make end-of-the-month deposits to the fund as well. He later finds a fund that promises to pay a guaranteed APR of 5 percent compounded monthly. Prof. ME decides to transfer the $120,000 to this new fund and make the necessary monthly deposits. How large of a monthly deposit must Prof. ME make into this new fund to meet his $440,000 goal? d. Now Prof. ME gets sticker shock from the necessary monthly deposit he has to make into the guaranteed fund in the preceding question. He decides to invest the $120,000 today and $350 at the end of each month for the next 8 years into a fund consisting of 50 percent stock and 50 percent bonds, and hope for the best. What APR would the fund have to earn for Prof. ME to reach his $440,000 goal? a. If Prof. ME invested $140,000 into a fund 2 years ago and hoped to have $440,000 available 10 years later when his first child started college, what was the original APR needed to reach his goal? \% (Round to two decimal places.) b. Now with only $120,000 in the fund and 8 years remaining until his first child starts college, what APR would the fund have to earn to reach Prof. ME's $440,000 goal if he adds nothing to the account? \% (Round to two decimal places.) c. If Prof. ME decides to transfer the $120,000 to a new fund that promises to pay a guaranteed APR of 5 percent compounded monthly and makes the necessary end-of-the-month deposits, how large of a monthly deposit must he make into this new fund to meet his $440,000 goal in 8 years? (Round to the nearest cent)
Answers
a. To calculate the original annual rate of return needed to reach Prof. ME's goal, we can use the future value formula:
Future Value = Present Value × (1 + Rate)^Time
Given that Prof. ME invested $140,000 and wanted to have $440,000 in 10 years, we can rearrange the formula to solve for the rate:
Rate = (Future Value / Present Value)^(1/Time) - 1
= ($440,000 / $140,000)^(1/10) - 1
Calculating this expression:
Rate ≈ (3.142857)^0.1 - 1
≈ 1.1072 - 1
≈ 0.1072
The original APR needed to reach Prof. ME's goal was approximately 10.72%.
b. With $120,000 in the fund and 8 years remaining until his child starts college, we can use the same future value formula to calculate the required APR:
Future Value = Present Value × (1 + Rate)^Time
Given that Prof. ME wants to reach a goal of $440,000 and adds nothing to the account, we solve for the rate:
Rate = (Future Value / Present Value)^(1/Time) - 1
= ($440,000 / $120,000)^(1/8) - 1
Calculating this expression:
Rate ≈ (3.666667)^0.125 - 1
≈ 1.0574 - 1
≈ 0.0574
The APR the fund would need to earn to reach Prof. ME's $440,000 goal is approximately 5.74%.
c. To determine the monthly deposit required to reach the $440,000 goal with a guaranteed APR of 5% compounded monthly, we can use the future value of an ordinary annuity formula:
Future Value = Payment × [(1 + Rate/12)^(Time×12) - 1] / (Rate/12)
Given that the future value is $440,000, the rate is 5% (0.05) compounded monthly, and the time is 8 years, we can rearrange the formula to solve for the payment:
Payment = Future Value × (Rate/12) / [(1 + Rate/12)^(Time×12) - 1]
= $440,000 × (0.05/12) / [(1 + 0.05/12)^(8×12) - 1]
Calculating this expression:
Payment ≈ $440,000 × 0.004167 / [(1 + 0.004167)^(96) - 1]
≈ $440,000 × 0.004167 / (1.004167^96 - 1)
≈ $440,000 × 0.004167 / (1.461765 - 1)
≈ $440,000 × 0.004167 / 0.461765
≈ $3,960.84
Prof. ME must make a monthly deposit of approximately $3,960.84 to meet his $440,000 goal in 8 years.
d. To calculate the required APR for Prof. ME to reach his $440,000 goal by investing $120,000 today and $350 at the end of each month for 8 years, we can use the future value of an annuity formula:
Future Value = Payment × [(1 + Rate/12)^(Time×12) - 1] / (Rate/12)
