Can you teach me how to solve the problem below

An educator conducted an experiment to test whether new directed reading activities in the classroom will help elementary school pupils improve some aspects of their reading ability. She arranged for a third grade class of 21 students to follow these activities for an 8-week period. A control classroom of 23 third graders followed the same curriculum without the activities. At the end of the 8 weeks, all students took a Degree of Reading Power (DRP) test, which measures the aspects of reading ability that the treatment is designed to improve. Run an independent samples t-test that will test for differences between the treatment and control groups. Also include a 90% Confidence Interval for the mean difference.

1. The researcher from the Annenberg School of Communications is interested in studying the factors that influence how much time people spend talking on their smartphones. She believes that gender might be one factor that influences phone conversation time. She specifically hypothesizes that women and men spend different amounts of time talking on their phones. The researcher conducts a new study and obtains data from a random sample of adults from two groups identified as women and men. She finds that the average daily phone talking time among 15 women in her sample is 42 minutes (with a standard deviation of 6). The average daily minutes spent talking on the phone among 17 men in her sample is 38 (with a standard deviation of 5). She selects a 95% confidence level as appropriate to test the null hypothesis.

a) Please identify the independent variable for the researcher's hypothesis in the text box below.

b) What is the unit of analysis?

c) What is the alpha?

d) State the research and null hypothesis in symbols. Make sure to be as complete as possible (Using H₁: and H₀:).

For each conjecture below, you are to describe in words what Ho and H a are. Consider the decision that you have to make based upon your conjectures. Then make a chart similar to the ones I created and fill in words what the Type I and Type II errors mean. Finally, describe the ramifications of making these errors within the context of the problem and describe which of the 2 errors are worse (in your opinion).

1. It is believed that a new drug can cure a cold.

2. The teacher will never check homework today.

3. In a big store like Walmart, they will never catch me if I shoplift.

4. Saddam Hussein has weapons of mass destruction. (this was the conjecture several years ago)

5. If I try to learn to ski, I will end up hurting myself.

6. I won’t apply to the University of Pennsylvania because I am sure I’ll never get in.

7. There might be a bomb in the school because someone called in a threat. We should evacuate.

8. Heaven and Hell exist

USE C language :- The use of computers in education is referred to as computer-assisted instruction (CAI). Write a program that will help an elementary school student learn multiplication. Use the rand function to produce two positive one-digit integers. The program should then prompt the user with a question, such as
How much is 6 times 7?

The student then inputs the answer. Next, the program checks the student’s answer.

• If it’s correct, display the message "Very good!" and ask the student if she/he would like to continue. If no terminate the program. if yes ask another multiplication question.
• If the answer is wrong, display the message "No. Please try again." and let the student try the same question repeatedly until the student finally gets it right.

A separate function should be used to generate each new question. This function should be called once when the application begins execution and each time the user answers the question correctly.

Before ending the program, the program should display how many questions were right and how many questions were answered wrong at the first time it was answered.

1. (a) Kyan Barron has been made jobless from a managerial position in a financial institution in

Kyan wishes for you to take into consideration: the tax (corporate and individual) structure, available allowances, National Insurance/Social Security costs, Value Added Tax/GST arrangements and the economic development in Barbados and St. Lucia.

You are a financial analyst for a company that is developing a new resort in Hawaii and the firm is in the process of purchasing 10 gold carts to carry potential condominium buyers around the property. You are choosing between one made by Club Car or one made by Yamaha. The two carts are judged to be similar in utility, but the Club Car is made more durably and is expected to have an effective working life of 5 years, compared to 4 for the Yamaha. Your firm’s tax rate is 35% and the required rate of return on this investment is 8%. Either one would be deprecated over its useful life to a salvage value of zero. At the end of their effective life, the carts will be donated to a local school system and so will have zero estimated salvage value. Which cart should the firm purchase? The following information is available:

Club Car:

Purchase price: $22,000

Annual Maintenance Expense: $1,900

Salvage Value at Life End: $0

Yamaha:

Purchase price: $19,000

Annual Maintenance Expense: $2,100

Salvage Value at Life End: $0

In September 2008, Lehman Brothers went bankrupt. Lehman’s assets in Asia and Europe were purchased by Nomura for the bargain price of $200 million. Founded in 1925, Nomura is the oldest and largest securities brokerage and investment banking firm in Japan. Although Nomura had operated in 30 countries prior to the Lehman deal in 2008, it had always been known as a significant but still primarily regional (Asian) player in the big league of the financial services industry. The deal was expected to boost Nomura’s presence in investment banking. Four years later, the performance has been disastrous, with Nomura losing an aggregate of $440 million since its Lehman acquisition.

Q1: What is the strategic fit between Nomura and Lehman?

Q2: Is there any organizational fit? How can the gaps between the cultures of these two firms be bridged?

Q3: How does Nomura alleviate the concerns of multiple stakeholders?

Q4: How would you predict the effectiveness of Nomura’s transformation after this acquisition to be?

Consider the following data.   

If the database administrator in the University has turned off auto-commit, consider the following:

UPDATE STUDENT

SET CLUBID = “PDC”

Answer the following:

1. How does the above SQL statement produce false information in the Student table?

Mary is a typical American girl who drives a jeep and wears jeans with holes in the knees and white t-shirts. She has an image of herself as slightly overweight. She exercises regularly, eats carefully, and tends to drink diet sodas to avoid those extra calories. She meets John, who has a great sense of humor and rarely wears shoes. They soon marry and begin to have children. They appear to be two normal parents, but their first son has some severe developmental delays. Undaunted, they have more children-- two boys and two girls, one of which has the same issue as the first son. Mary thinks that John isn’t telling the truth about his family, who she has never met, and that he has “bad genes”. John thinks it is something Mary does and his ardor for her wanes. So Mary switches to wearing dresses. Since Mary notices that this changes her appearance, she stops dieting, but continues to eat carefully and exercises and gets her whole family to do so. Her image of herself improves, and so does their relationship. They have five more children, none of which are retarded. John feels vindicated and Mary begins to feel guilty. Once again marital troubles arise. Because of their strong commitment to one another, John and Mary decide to visit their minister, who is also a genetic counselor. He has an idea and suggests some tests on the children. The retarded children showed serum phenylalanine concentrations several times the normal. Tests on fragments of the DNA from chromosome 12 indicate that of the first five children, the normal children each have at least one copy of the DNA most people have. (Which allele would these children have?) The developmentally delayed children have two unusual copies. (Which allele would these children have?) In the second set of five children, one of the children has two copies of the normal DNA, two have only one copy, and two have none of the normal sequence of DNA. (What would be the genotypes in each of these cases?) The night the minister is to meet with John and Mary to explain this to them, his car is found on the side of the road with the folder containing this information, two empty cans of diet Dr. Pepper, and a single white rose. The minister was never found. Your team of genetic counselors is called in to explain the cause of the developmental delays to John and Mary and to explain what, if anything, they can do about it. Fill in the information requested below.(5pts) [note: you may need to look outside your text book for help in answering this question. Hint – what warning appears on the label of diet drinks containing aspartame?] You may need to look up some information on aspartame.

1. Based on the information provided in the story, what are John and Mary’s genotypes? John’s __________ Mary’s ____________ How do you know?

2. If John and Mary were to have another child, what is the probably that they would have a child that could possibly have a problem with mental retardation (particularly if they don’t pay attention to diet)? Use the Punnet square below to help with your answer (you must fill it out for full credit!)

3. What can you tell John and Mary about the cause of the developmental delays in their children? Is just having the “right” genotype enough or are there other factors involved?
