A wildlife analyst gathered the data in the table to develop an equation to predict the weights of bears. He used WEIGHT as the dependent variable and CHEST, LENGTH, and SEX as the independent variables. For SEX, he used male=1 and female=2. Using Microsoft Excel, perform a regression analysis and find R-squared, adjusted R-squared, and the p-value for the regression. y=dependent x=independent

1) If nondisjunction occurs during meiosis II, what type of gametes would be expected?
2) Sex determination in Ewoks is similar to humans - female Ewoks have two X chromosomes and males have one X and one Y chromosome. A gene on the X chromosome determines eye color, where the dominant allele XB gives produces black eyes and the recessive allele Xb produces hazel eyes. Two black eyed parents have a hazel eyed son. If they have two additional children, what is the chance they will have a black eyed daughter and a black eyed son? Write your answer as a fraction, such as 1/2, 1/4, 1/8, 3/16 or .

Credit card numbers typically consist of 13, 15, or 16 digits. For example,
4690 3582 1375 4657
is a hypothetical credit card number. The first digit designates the system. In (3.1.1), the first digit, 4, shows that the card would be a Visa card. The following digits specify other information such as the account number and bank number. (The precise meaning depends on the type of card.) The last digit it special; it is computed from the previous digits and is called the check digit. In (3.1.1), the check digit is 7 and is computed from the previous digits 4690 3582 1375 465. Credit card check digits are used to identify certain erroneous card numbers. It is not a security measure, but rather it is used to detect errors such as giving a credit card number over the phone and having it transcribed improperly or detecting an error in entering a credit card number while ordering a product online.
The check digit is computed as follows. Start from the right and skipping the check digit, double every other number. If the result of doubling is a two-digit number, addthe digits; otherwise, use the original digit. The other digits are not modified.
4 6 9 0 3 5 8 2 1 3 7 5 4 6 5
8 6 18 0 6 5 16 2 2 3 14 5 8 6 10 >>>>>>>>Double every other digit.
8 6 9 0 6 5 7 2 2 3 5 5 8 6 1 >>>>>>>>Add digits of two-digit numbers.
Sum the resulting digits
8+6+9+0+6+5+7+2+2+3+5+5+8+6+1=73.
If the last digit of the sum is 0, the check digit is 0. Otherwise, subtract the last digit of the sum from 10 to get the check digit, 10-3=7. Verify the check digit on your favorite Visa, Mastercard, AMEX, or Diners Club card. This method of calculating a check digit is called the Luhn algorithm. It is named after Hans Peter Luhn (1896-1964), who invented it while at IBM. Although originally patented, it is now in the public domain and is widely used.
For this project you will write a program that implements the Luhn algorithm given above (use the above method not another variation) for computing a credit card check digit. There will be three parts to this project. It has to in java code.
Part-1
Work the algorithm by hand. Read the description of the algorithm above and work it by hand for a credit card or debit card number you might have. You can use the hypothetical credit card number in the discussion above. Compute the credit card check digit by hand. Write out the steps neatly. Do it several times until you understand how it works. Write it up neatly, scan it and upload to Canvas. This will be the first of three items to turn in this project.
Part-2 Write up a program algorithm (pseudo code).
Once you understand the algorithm write pseudocode that will describe how you will write you program. The conditions of the program are as follows.
Enter a credit card number with an even number of digits:
4690358213754657
CSC-201 Computer Science I
Programming Project 2
Name:
Credit Card Number Entered 4690 3582 1375 4657
The check digit is 7
Part-3
Use you pseudo code to help you code the program in Java. Test your program using credit card number above (4690358213754657) Test it with other credit card numbers you might have. Once you have the code completed and tested upload the source .java file to canvas. This is the third of three items you will turn in.

Palencia Paints Corporation has a target capital structure of 35% debt and 65% common equity, with no preferred stock. Its before-tax cost of debt is 8%, and its marginal tax rate is 40%. The current stock price is P0$22.00. The last dividend was D0$2.25, and it is expected to grow at a 5% constant rate. What is its cost of common equity and its WACC?

A researcher was curious about whether people’s attitudes are related to their behaviors. As a simple experiment, the researcher measured people’s attitudes and behaviors regarding housework.
On the attitude side, the researcher measured the level of agreement on the statement “It is much better for everyone involved in housework: strongly agree, agree, disagree, and strongly disagree” On the behavioral side, the respondents are asked to estimate how many hours of housework they do per week.
Based on your analysis of the data below, please come up with a conclusion whether people who respond differently to the attitudinal question actually behave differently?
Once you have arrived at an answer to each question, please write a sentence or two interpreting the result (100 pts).

You are a profit-maximizing firm. Suppose there are two types of customers (50% of 1 type, 50% of the other) who shop in your specialty clothing store. Consumers of type R will pay __B__ for a coat and __C__ for pants. Consumers of type S will pay __D__ for a coat and __E__ for pants. Your firm faces no competition and but it does pay for the clothing, __F__ per coat and __G__ per pair of pants, i.e. MCcoat = __F__ and MCpants= __G__. You can't price discriminate. You offer the same prices to all your customers.
(Show your work) (A) (2 pts.) Suppose you post a price for a coat and a price for pants. What are the profit-maximizing prices to charge?
Answer: Price for coat = $_______ ; Answer: Price for pants =$_________
(B) (2 pts.) Suppose instead that you only offer a bundle of one coat and one pair of pants (which we would call a suit.) What is the profit-maximizing price to charge for the suit?
Answer: Price for suit = $_______
( C) (2 pts.) Answer True or False and then show or explain how you reached your conclusion: Profits in Part (B) with bundling are higher than in Part (A) of this problem. Answer: ________________
