Suppose the health scores for the panda population has a mean of 100 and a standard deviation of 20. The health scores for the hippo population has a mean of 100 and a standard deviation of 50. Which researcher is more likely to get a sample mean of 80 or lower? A. Researcher A B. Researcher B

Q9 A sample of 100 people was taken from a population with a mean of 50 and a standard deviation of 20. What is the typical amount that the sample mean deviates from the population mean? A. 1 B. 1.5 C. 2 D. 2.5

You have 100 coins, and 99 of them are fair (equal probability of heads or tails). One of them is weighted and has a 90% probability of landing on heads. You randomly choose one of the 100 coins. Find the probability that it is a weighted coin, under the following scenarios: (Hint: if your calculator can’t compute 100!, R can, just type factorial(100))

(a) You flip it 10 times and lands on heads 10 times (b) You flip it 10 times and it lands on heads 9 times

(c) You flip it 20 times and it lands on heads 18 times (d) You flip it 100 times and it lands on heads 77 times

In your opinion, what may be the three most powerful barriers to entry? Why? Please give an example of each of these three barriers to entry. 4. In your opinion, which three barriers may be the least powerful? Why? Please give an example of these three barriers to entry. 5. Please give three examples of how “consumer loyalty” may be used as a barrier to entry and success, and please try to use examples not previously discussed, if possible. 6. Please give three examples of how our legal system may be used as a barrier to entry and success, and please try to use examples not previously discussed, if possible. 7.

Ericsson is a large global company providing hardware, software, and related services for radio-access networks within mobile telecommunication systems. Assume that it is developing a new networking system for smaller, private telephone companies. To attract small companies, Ericsson must keep the price low without giving up too many of the features of larger networking systems. A marketing research study conducted on the company’s behalf found that the price range must be $50,000 to $75,000. Management has determined a target price to be $65,000. The company’s minimum profit percentage of sales is normally 15%, but the company is willing to reduce it to 12% to get the new product on the market. The fixed costs for the first year are anticipated to be $8,000,000. If sales reach 400 installed networks, the company needs to know how much it can spend on variable costs, which are primarily related to installation.

1. What is the amount of total cost allowed if the 12% profit target is allowed and the 400 installations sales target is met? Show the amount for fixed and for variable costs.

2. What is the amount of total costs allowed if the 15% normal profit target is desired at the 400 installations sales target? Show the amount for fixed and for variable costs.

3. Discuss the advantages of using a target costing model versus using cost-based pricing.

You and your friend Jack have different opinions about Tesla stock price. On Sep. 30, 2020, you did a short sale of Tesla stock at $429.01 for $1000 shares. The same day, Jack bought the Tesla stock at $429.01 for $1000 shares with margin. The initial margin and maintenance margin requirement for short sale is 150%. The initial margin and maintenance margin requirement for long on margin is 30% (assume no interest is charged on long on margin account). Below is the Tesla stock price in the next 2 days:

Oct. 01, 2020          $448.16

Oct. 02, 2020          $415.09

What is your expectation of Tesla stock price change in the future? (1 point)

What is Jack’s expectation? (1 point)

Please calculate your daily margin ratio and Jack’s daily margin ratio for each of the next 2 days

(Oct. 01 and Oct. 02). Please specify if margin call is received and how much money you or Jack

need to deposit into the account after the margin call. (6 points)

If you and Jack both decide to close the account (i.e., selling the stock or covering the short selling position) after receiving the first margin call instead of depositing more money into the account, please calculate returns for both of you. (4 points)

James Kelvin just completed an Engineering Management degree program, main reason is to enhance his investment capability. Now, he wants to take advantage of the falling prices of crude oil to invest in the oil business, with an anticipation that the prices will rise again. He has been offered an oil well with a proven reserve of 1800000 barrels. From his feasibility study, he will be able to produce 80,000 barrels of oil during the first year of operations. He believes that as the production capacity increases, he will increase the oil production by 10% annually, starting from the second year. A financial institution has offered to finance this investment at 9% interest rate compounded annually. From historical data, the price of oil is expected to remain steady at $30 per barrel over the next three years and start to increase thereafter at the rate of 8% annually for the next 5 years. When the price is peaked at the end of the 8th year, it stays steady for the next 4 years. He hopes to sell the oil well at the end of 10 years of operations for $5,000,000. What is maximum price (to break even) that James should buy the oil well now? (in order words, in other words, what will be the present worth of this investment).

Aspen Recreation Company sells three products today. The first product is called the Apache Classic Dunebuggy and they sell 400 units each year. The second product is called the Apache Basic Dunebuggy and they sell 550 units each year. The third product is called the Apache Deluxe Dunebuggy and they sell 300 units per year. Aspen Recreation is thinking about launching a fourth product called the Apache Gen Z Dunebuggy. If they launch this Gen Z Dunebuggy, they expect to be able to sell 475 units annually. But, if they launch the Gen Z Dunebuggy, there will be impacts on their current products. The Apache Classic Dunebuggy will have a sales decline to 275 units each year. The Apache Basic Dunebuggy will have an expected sales increase to 575 per year. There will be no change in the sales of the Apache Deluxe Dunebuggy. The selling price for the Apache Classic Dunebuggy is $13,900 each. The selling price for the Apache Basic Dunebuggy is $7,000 each. The selling price for the Apache Deluxe Dunebuggy is $18,000 each. The proposed new Apache Gen Z Dunebuggy is expected to sell for $9,000 each. For purposes of analyzing the costs and benefits of potentially launching this new product, the Apache Gen Z Dunebuggy, what is the appropriate annual amount of sales you should use in your analysis?

Independent t-test (assuming unequal variances) for mass per pot at the 50 pot and 100 pot comparing radish to tomato. Is this asking to perform a t-test with tomato at 50 and radish at 50 and another t-test with tomato at 100 and radish at 100 or tomato at 50 and tomato at 100 and radish at 50 and raidsh at 100
