Firms HL and LL are identical except for their financial leverage ratios and the interest rates they pay on debt. Each has $15 million in invested capital, has $3 million of EBIT, and is in the 40% federal-plus-state tax bracket. Firm HL, however, has a debt-to-capital ratio of 50% and pays 12% interest on its debt, whereas LL has a 35% debt-to-capital ratio and pays only 10% interest on its debt. Neither firm uses preferred stock in its capital structure. Calculate the return on invested capital (ROIC) for each firm. Round your answers to two decimal places.

ROIC for firm LL is %

ROIC for firm HL is %

Calculate the rate of return on equity (ROE) for each firm. Round your answers to two decimal places.

ROE for firm LL is %

ROE for firm HL is %

Observing that HL has a higher ROE, LL's treasurer is thinking of raising the debt-to-capital ratio from 35% to 60% even though that would increase LL's interest rate on all debt to 15%. Calculate the new ROE for LL. Round your answer to two decimal places.

chi-squared test ( χ2 test) problem
We're interested in the weight of babies born not prematurely but after a pregnancy shorter than average. Of a sample of 300 children born in April, the found as follows:

. born after 37 weeks: 30 slightly underweight; 20 normal weight.

. born after 38 weeks: 40 slightly underweight; 60 normal weight.

. born after 39 weeks: 50 born slightly underweight; 100 normal weight.

(a) Identify the two variables studied in the sample and the values of the two variables they can take, then build a full frequency table.

b) Calculate the value χ2 from the table obtained in a). Explain why we can be almost certain that there is an interdependence between the number of weeks of pregnancy and birth weight.

(c) As it has been found that there is an interdependence between the two, an attempt will be made to establish a numerical relationship between the number of weeks of pregnancy and the proportion of children born underweight. What will our variables be here and what does our study tell us?

d) Calculate the equation for the regression line obtained from the points found in c).

Write a method, makeUserName, that is passed two Strings and an int: the first is a first name, the second is a last name, and the last is a random number. The method returns a user name that contains the last character of the first name, the first five characters of the last name (assume there are five or more characters in last name), and the random number. An example: Assume that “John”, “Smith”, 45, are passed when the method is called, it will return “nSmith45” as the user name.

Last year, Paul and Joanna Stillman bought a home with a dwelling replacement value of $200,000 and insured it (via an HO-5 policy) for $176,000. The policy reimburses for actual cash value and has a $500 deductible, standard limits for coverage C items, and no scheduled property. Recently, burglars broke into the house and stole a 3-year-old television set with a current replacement value of $700 and an estimated useful life of 9 years. They also took jewelry valued at $2,400 and silver flatware valued at $3,200.?

Assuming a 50% coverage C limit, calculate how much the Stillmans would receive if they filed a claim for the stolen items?

Round the answer to two decimal places.? $________

1. A good quality lawnmower is supposed to start at the first try. In the third quarter, 50 craftsman lawnmowers are started every day and an average of 4 did not start. In the fourth quarter, the number of lawnmower did not start (out of 50) in the first 6 days are 4, 5, 4, 6, 7, 6, respectively. Was the quality of lawnmower changed in the fourth quarter?

2.There have been complaints that the sports page of the Dubuque Register has lots of typos. The last 6 days have been examined carefully, and the number of typos/page is recorded below. Is the process in control?

First, visit the following websites on insider trading: Securities and Exchange Commission (SEC) website regarding insider trading. SEC enforcement actions (insider trading cases) These websites will help you become familiar with the general basics of the regulatory rules applying to insider trading. You are not expected to become an expert on this topic. Apply these rules to the facts of this very brief case: Someone you know has knowledge of an impending merger between two companies. The combination of the two firms will certainly change the market dynamics of the industry. Moreover, owners of stock in both companies will greatly benefit once the news of the merger is publicly announced. Project Requirements Your presentation must consist of 6 to 7 slides that are clear, legible and address the following: Discuss the general basics of the regulatory rules applying to insider trading and its implications and address the following: Legal implications Ethical implications Economic-social implications You must include a title slide in addition to the six to seven slides. The title page must include: The title of the project The names of the group members The area where the team member provided initiative (contributed to the project). Each slide will include a bulleted list highlighting important aspects of your research. Details of your research and citations will be presented in the notes section of each slide in the presentation.

Janine is considering buying a water filter and a reusable water bottle rather than buying bottled water. Will doing so save her money?
First, determine what information you need to answer this question, then click here to display that info (along with other info).

• How much water does Janine drink in a day? She normally drinks 6 bottles a day, each 16.9 ounces.
• How much does a bottle of water cost? She buys 24-packs of 16.9 ounce bottles for $3.19.
• How much does a reusable water bottle cost? About $10.
• How long does a reusable water bottle last? Basically forever (or until you lose it).
• How much does a water filter cost? How much water will they filter?
  • A faucet-mounted filter costs about $28 and includes one filter cartridge. Refill filters cost about $33 for a 3-pack. The box says each filter will filter up to 100 gallons (378 liters)
  • A water filter pitcher costs about $22 and includes one filter cartridge. Refill filters cost about $20 for a 4-pack. The box says each filter lasts for 40 gallons or 4 months
  • An under-sink filter costs $130 and includes one filter cartridge. Refill filters cost about $60 each. The filter lasts for 500 gallons.

Which option is cheapest over one year (365 days)?
The cheapest option saves her $______ over a year.
Give your answer to the nearest cent. Pro-rate the costs of additional filters (so if you only use part of a filter, only count the corresponding fraction of the filter cost).
