While playing the role of Catherine Piper on Boston Legal, Betty White “killed” the character of Bernard Ferrion (played by Leslie Jordan). Catherine ended being found not guilty, but it led Betty to wonder: are men and women treated differently when convicted of murder? As a result, Betty took two random samples of convicted murderers, given below, and determined how long the sentences were. Men: 25, 30, 50, 25, 20, 30, 40, 25, 30, 25, 75, 25, 15 Women: 25, 15, 20, 15, 20, 25, 15, 30, 25, 40 You may assume the data comes from normal distributions. At the .05 level of significance, is there evidence to show that men get longer sentences for murder than women?

ABC’s the most recent free cash flow (FCF0) is $200 million. The free cash flow is expected to grow at a rate of 40 percent, and 20 percent in the second year. After two years, it is expected to grow forever at a constant rate of 5 percent. The cost of common stock (rs) is 12% and the weighted average cost of capital (WACC) is 9%. ABC balance sheet shows $20 million in short term investments that are unrelated to operations. The balance sheet also shows $100 million in debt, $50 million in preferred stocks, and $250 million in common stocks.If the company has 40 million shares of common stocks, what is your best estimate for the stock price per share today? Assume that company's book values of debt and preferred stocks are very close to the market vales.

Create Java game on How to play Bulls and Cows between you (the host) and your computer (the player)
When completed, your program allows you to host the game (i.e., you create a secret word and score every guess) and it makes guesses until it wins.
In this player mode, your program should:
1. Display a total count of guesses with a new generated guess, which should be a 5-char string with '@' always included and the rest four characters drawn from any of the below 3 sets
characters:
{A, B, C, D, E}
{ 5, 6, 7, 8, 9 }
{ =, ?, %, @, $ }
2. Wait for a score (e.g., '2Bull, 3Cow') to be returned and entered by the host, who is you. It's suggested the score is entered on the same line of the the count and guess displayed in the above step. So, it would look like
Guess #3 8@XYZ 1Bull, 2Cow
Guess #4 5@WYZ 1Bull, 1Cow
Guess #5 @8=%Z 4Bull, 0Cow
Repeat the above two steps until the guess wins a score of '5Bull, 0Cow' as shown below.
Guess #3 8@XYZ 1Bull, 2Cow
Guess #4 5@WYZ 1Bull1Cow
Guess #5 @8=%Z 4Bull, 0Cow
Guess #6 @8=6Z 5Bull, 0Cow -- You won!!
Except for the very first guess, your program should implement a strategy or formula to generate a new guess based on all scores collected. A good strategy or formula should use as much as possible the information or hints provided by the scores to quickly approach the secret word. This would be the most challenging component to be implemented in the entire program.
Hint: one possible method is to generate a list of all possible secret words (using all scores returned) that could be the next guess, then to prune the list by keeping only those words that would give an equivalent score to how the last guess was scored. Then, the next guess can be any word from the pruned list. Either the guess correctly hits the secret word or run out of words to guess, which indicates a problem with the scoring or a problem with the list itself.
Please, keep in mind that the computer is the player, the one that has to guess the inputted String by the user.

A tire distribution centre supplies various mechanic shops around the province and sells on average 40 sets (4 tires to a set) of one specific tire each week. These tires are supplied by an overseas manufacturer. The following information is known about the tire sets:
| Weekly average tire set demand (µ) 40 |
| Weekly tire set demand standard deviation (σt) 8 |
| Weekly holding cost per tire set $18.00 |
| Order cost per order $45.00 |
| Lead time 1 weeks |
| Working weeks per year 50 weeks |
The company currently uses a periodic review inventory control system with a period (P) of 8 weeks.
(1) Given that the distribution centre wants a 99.5% service level, what is the required safety stock?
(2) What is the required target inventory level (T)?
(3) Calculate the annual inventory cost of this periodic review system.
(4) The company is committed to a periodic review system, but thinks it may be incurring unnecessary costs. Suggest a better period (P) that will decrease the annual inventory cost. What is the expected cost of your proposed P?

With some services, e.g., checking accounts, phone service, or pay TV, a consumer is offered a choice of two or more payment plans. One can either pay a low entry fee and get a high price per unit of service or pay a high entry fee and a low price per unit of service. Suppose you have an income of $1000. There are two plans. Plan A has an entry fee of $20 with a price of $10 per unit. Plan B has an entry fee of $40 with a price of $5 per unit for using the service. Let ?2 be expenditure on other goods (i.e., ?2 is the numeraire) and let ?1 be the consumption of the service. Your utility function is given by ?(?1, ?2) = 100(?1)^(1/2) + ?2.
1) Write down the budget equation that you would have after you paid the entry fee for each of the two plans. (6 points)
2) Find the demand functions. (10 points)
3) How much service would you use in each case? And how much would you
spend on other goods? Clearly derive your results. (8 points)
4) Which plan would you prefer? Explain. (6 pints)
