Left ventricular mass (LVM) is an important risk factor for subsequent cardiovascular disease. A study is proposed to assess the relationship between childhood blood pressure levels and LVM in children as determined from echocardiograms. The goal is to stratify children into a normal bp group (< 80th percentile for their age, gender, and height) and an elevated bp group (≥ 90th percentile for their age, gender, and height) and compare change in LVM between the 2 groups. Before this can be done, one needs to demonstrate that LVM actually changes in children over a 4-year period.

To help plan the main study, a pilot study is conducted where echocardiograms are obtained from 10 random children from the Bogalusa Heart Study at baseline and after 4 years of follow-up.

Implement an appropriate 2-sided test to test the hypothesis that there is a change in mean LVM over 4 years?

You must clearly write out all 4 steps of the appropriate hypothesis test clearly defining the parameter(s) involved, calculate the value of the test statistic and the p-value, and state your conclusion in the context of the problem.

3. (a) California Bank holds $375 million in deposits and maintains a reserve ratio of 5%. Show the T-account of the bank

Money Multiplier =

Final Money Supply =

(b) If First Bank has deposits = $500,000, reserves = $100,000, and loans = $400,000. Show the T-account of the bank:

If the Fed requires banks to hold 5% as reserves:
Required Reserves =

Excess Reserves =

Final Money Supply =

(c) If First Bank decides to decrease its reserves to the required amount. Show the new T-Account of the bank.

Final Money Supply =

(d) The banking system has $100 billion of reserves, none of which are excess. People hold only deposits and no currency, and the reserve requirement is 40%. Show the T-Account of the banks.

this question I will cancel because I dont need it now Thanks for your response. I will be posting the actual question in about 20 minutes

Marc and Michelle are married and earned salaries this year of $64,000 and $12,000, respectively. In addition to their salaries, they received interest of $350 from municipal bonds and $500 from corporate bonds. Marc contributed $2,500 to an individual retirement account, and Marc paid alimony to a prior spouse in the amount of $1,500 (under a divorce decree effective June 1, 2005). Marc and Michelle have a 10-year-old son, Matthew, who lived with them throughout the entire year. Thus, Marc and Michelle are allowed to claim a $2,000 child tax credit for Matthew. Marc and Michelle paid $6,000 of expenditures that qualify as itemized deductions and they had a total of $3,500 in federal income taxes withheld from their paychecks during the year.

a. What is Marc and Michelle’s gross income?

b. What is Marc and Michelle’s adjusted gross income?

c. What is the total amount of Marc and Michelle’s deductions from AGI?

d. What is Marc and Michelle’s taxable income?

e. What is Marc and Michelle’s taxes payable or refund due for the year?

What is ethical in one country may be unethical       or illegal in other countries – and vice versa. Nevertheless, ethical imperialism (absolute belief that “there is only one set of Ethics, and we have it!”) is alive and well.  You may be able to identify some values that seem to be almost universally accepted.  However, such is not the case with all values.  As a result, does a global company need to “pick sides” in ethical controversies and thus be an “ethical imperialist?” (10 marks; max 1000 words).

Q2:

Starting at the equilibrium point called “A” of Demand for money curve (DM) and Supply of money (MS1). Now suppose Bank of Canada increases money supply to MS2, and the value of money and price level adjust to bring supply and demand for money into a new equilibrium point called “B”. EXPLAIN CAREFULLY THE ADJUSTMENT PROCESS OR WHY THE ECONOMY MOVES FROM point “A” to point “B”?

Q3:

Consider the following relation:

Student-Dept = (Student-ID, Course, SportActivity, Dept-Name, Building)

Having following multivalued dependencies:

            F ={ Student-ID ®® Course

                   Student-ID ®® SportsActivity               

      Dept-Name ®® Building }

Explain in your own words why the Student-Dept relation is not in 4NF. Then, convert the Student-Dept relation in 4NF. Also, provide the justification for each step you perform during normalization (4NF). Note: The SportActivity here means any sport a student is participating in. For example, a student with ID = 123 can participate in soccer and badminton.

Q4:

In your own word, explain why do designers use Denormalization? What is the limitation of using Denormalization? Name and explain a better alternative approach than Denormalization.

Write this in java please. I use Eclipse

Write the following two functions. main doesnt need to be filled up.

Function 1:

Write a function called howMany that takes two arguments: an array of integers called arr, and an integer called iTarget. The function should return an integer result. Inside the function write a loop to go through the array and count the number of elements in the array that have the same value as iTarget. At the end it should return the count as the function return value.

Function 2:

Write a function called endsIn that takes two arguments: a String and a character. The function should return true if the string ends in that character or else return false. (Only if the ending character of the string is the character passed in as an argument.)

You sell the book “JAVA for Fools”. Write a program that has you enter a years worth of monthly sales (in terms of money). Create an array of string objects initialized to the month strings. The program should use a loop to prompt you by month from this created array of months and storing the input data (sales numbers for each month) in an array of double. Then the program should find the sum of the array contents and report the total sales for the year.

The Kingdom of Mars, where the unit of currency is the Rock, has the following income tax code:

First 3,000 Rocks: 0% tax

Next 5,000 Rocks: 5% tax

Next 10,000 Rocks: 10% tax

Rocks after 18,000: 15% tax

For example, someone earning 30,000 Rocks would owe (3,000 × 0.00 + 5,000 × 0.05 + 10,000 × 0.10 + 12,000 × 0.15, or) 3,050 Rocks. Write a JAVA program that inputs incomes and calculates the tax owed in the Kingdom of Mars in Rocks.
