I'M HAVING A DIFFICULT TIME UNDERSTANDING HOW TO FIND/SOLVE THESE TYPES OF PROBLEMS:

In 2017, as reported by ACT Research Service, the mean ACT Math score was μ=20.6 μ=20.6 . ACT Math scores are normally distributed with σ=4.8 σ=4.8 .

1. What is the probability that a randomly selected test taker has an ACT Math score less than 18? Is this result unusual? Explain.
2. Describe the sampling distribution of x ˆ  x^ , the sample mean ACT Math score for a random sample of 40 tests using the N(mean, standard deviation) notation.
3. What is the probability that a random sample of 40 tests has a mean ACT Math score less than 18? Is this result unusual? Explain.
4. What is the difference in part a and c in this question?

A paint manufacturer’s latex paint requires 130 minutes, on average, to dry. A new additive is being tested to determine if it reduces the mean drying time of this paint. The drying times, in minutes, for a random sample of forty-five randomly selected cans of this manufacturer’s paint (with additive) are shown in the following table displays the data in minutes. Does this sample provide evidence that the additive reduces the paint’s drying time?

123 109 115 121 130 104 134 122 132 127 106 120 116 136 123 118 112 127 131 128 136 110 133 125 117 131 119 122 133 119 135 109 116 105 118 113 126 117 125 111 127 131 114 110 122

(e) Compute the P-value; report your answer with at least four digits after the decimal point. Write a sentence, or two, describing the process you used to determine the P-value. If, for example, you use a TI-84+ calculator or an iOS app or an Android app or Excel or StatCrunch, etc., state this, give the name of the specific function within that technology that you use, and describe the information you had to enter in order to execute the function. If, instead, you use an online app, provide the URL and describe the information you had to enter in order to execute the function. [1.5 pts]

(f) Use the appropriate symbols and values to communicate the specific conditional probability that the P-value represents in this specific problem and write a sentence, or two, describing the specific event in the context of this specific problem which has probability equal to the P-value of occurring. [1 pt]

(g) If this hypothesis test is performed at the 1% level of significance, what do you conclude? Please write your conclusion in plain English about whether-or-not the additive reduces the average drying time of this manufacture’s latex paint. [1.5 pts] (h) If the paint additive does not, in fact, reduce the drying time of this manufacturer’s latex paint, have you made either a Type I or Type II error in part

(h)? If you have made an error, tell which kind of error (Type I or Type II) you made and explain why; if no error has been made, explain why

1. explain how to find the stationary state in a Solow model

2. Explain how the economy behaves out of the stationary state in a Solow model.

Public school policy at the state or local level. Give an example of how the actors in the local or state government and/or how the structure of the government affects decisions about the public.

You have gathered information about the expected returns and standard deviations of two stocks, which is given in the table below:

a. Discuss which stock is more attractive and why? (hint: think about the assumptions first)

You are going to form a portfolio, which includes these two stocks. The value of your total portfolio is 800 000 and investment into stock B is 60% of the total portfolio.

b. It is estimated that the correlation between the stock returns is -0.50. Explain, what does this result mean?

c. Calculate the portfolio risk and expected return, and explain the benefits of diversification.

(Show your work, you may upload the solution file)

2. Consider the Solow growth model. Suppose that the production function is constant returns to scale and it is explicitly given by: Y = K^aL^1-a

a. What is the level of output per capita, y, where y = Y/L?

b. Individuals in this economy save s fraction of their income. If there is population growth, denoted by n, and capital depreciates at the rate of d over time, write down an equation for the evolution of capital per capita, k, k = K/L over time, denoted by Δk.

c. On a Solow diagram show the steady state levels of k, y, c and i.

d. Assume that the country is in its steady state. Explain what happens if half the population dies and half of the capital stock, K, is lost due to civil conflict. Illustrate your answer on a Solow diagram.

Lynbrook, Inc. was formed on January 2, 2015 with the authorization to issue 300,000 shares of $10 par value common stock and 20,000 shares of $100 par value cumulative preferred stock. During 2015, all the preferred stock was issued at par, and 170,000 shares of common stock were sold for $25 per share. The preferred stock is entitled to a dividend equal to 8 percent of its par value before any dividends are paid on the common stock.

During its first five years of business (2015 through 2019), the company earned income totaling $4,200,000 and paid dividends of 40 cents per share each year on the common stock outstanding as of December 31.

On January 2, 2017, the company purchased 20,000 shares of its own common stock in the open market for $300,000. On January 2, 2019, it reissued 15,000 shares of this treasury stock for $270,000. The remaining 5,000 were still held in treasury at December 31, 2019.

Instructions

a. Prepare the stockholders' equity section of the balance sheet for Lynbrook, Inc. at December 31, 2019. Include supporting schedules showing (1) your computation of any paid-in capital on treasury stock and (2) retained earnings at the balance sheet date. (use the Review Problem at end of Chapter 10, page 550-552, as a guide for your solution)

b. At December 31, 2019, shares of the company's common stock were trading at $30. Explain what would have happened to the market price per share had the company split its stock 3-for-1 at this date. Also explain what would have happened to the par value of the common stock and to the number of common shares outstanding.
