A researcher surveyed 12 men who lost their fathers earlier in their lives.  His survey included the age of the subjects when their fathers died and their confidence that they would someday be happily married themselves (100 point scale – higher score = more confidence).  The results are shown below.

Mx=15 My =60

SSx=348 SSy=5198

SPxy=933

Write a short interpretation of the effect size.

Write the equation for the regression line.

State, in words, the meaning of the regression equation.

Can you estimate a confidence rating for a man who lost his father at 30 years old? Why or why not?

Qn3 The following program has syntax errors. Correct them. On each
successive line, assume that any preceding error has been corrected. After you have
corrected the syntax errors, type and compile the program to check if all errors have
been found.
public class Qn3
{
static final int SECRET_NUM = 11 ,213;
static final PAY_RATE = 18.35
public void main ( String [] arg)
{
int one , two;
double first , second
one = 18;
two = 11;
first = 25;
second = first * three ;
second = 2 * SECRET_NUM ;
SECRET_NUM = SECRET_NUM + 3
System .out. println ( first + " " + second + " "
+ SECRET_NUM );
paycheck = hoursWorked * PAY_RATE
System .out. println (" Wages = " paycheck );
}
}

Qn 4 )Write a program that prompts the user to input ve decimal numbers.
The program should then add the ve decimal numbers, convert the sum to the
nearest integer, and print the result.

In the book Business Research Methods (5th ed.), Donald R. Cooper and C. William Emory discuss a market researcher for an automaker who is studying consumer preferences for styling features of larger sedans. Buyers, who were classified as “first-time” buyers or “repeat” buyers, were asked to express their preference for one of two types of styling—European styling or Japanese styling. Of 40 first-time buyers, 8 preferred European styling and 32 preferred Japanese styling. Of 60 repeat buyers, 40 preferred European styling, and 20 preferred Japanese styling.

1) Create a cross-tabulation for the data (5 points)

2) Test the hypothesis that buyer status (repeat versus first-time) and styling preference are independent at the 0.05 level of significance. What is your conclusion? Show the procedure. (5 points)

A call option on a stock with a strike price of $60 costs $8. A put option on the same stock with the same strike price costs $6. They both expire in 1 year.

(a) How can these two options be used to create a straddle?

(b) What is the initial investment?

(c) Construct a table that shows the payoffs and profits for the straddle when the stock price in 3 months is $50, and $72, respectively. The table should looks like this:

4. Suppose that you are the engineer in the charge of the gasification section of the Acme Substitute Natural Gas Company. ASNG Co. runs fixed-bed, dry-ash gasifiers. The raw gas is cleaned, shifted, and sent to a methane synthesis unit. Every morning you receive a report from ASNG’s analytical laboratory on the characteristics of the coal that will be fed to the gasifiers during the next day’s operations. One important characteristic is the ash fusion temperature (AFT), i.e., the temperature at which the ash will begin to melt and form a liquid slag. It is vitally important to keep the bed temperature not only below the AFT, but usually ≥100°C below, to allow for a margin of safety. One day the lab report indicates that the AFT for the coal about to go to the gasifiers is substantially lower than it has been in recent weeks. (a) What instructions will you issue to the plant operators for adjusting the steam/oxygen ratio being fed to the gasifiers? (b) Why? (c) What impact will this change have on the H₂/CO ratio in the product gas? (d) Why? (e) How will this change affect operation of the water-gas shift unit? (f) Why?

Please show work (i.e. equations used) not just the final answer

4. Neonatal mortality rate
5. Abortion rate
6. Fertility rate
7. Age-specific mortality rate for women aged 55 years or older
8. Cause-specific mortality rate for those who died from heart disease
9. Cause specific mortality rate for those who died from stroke
10. Proportional mortality ratio for cancer among persons ages 55 years or older

In.java

Write down a program that asks the user for their full name given in the format first last. The program will do the necessary processing and print the name in a table with 3 columns: Last, First, Initials. Requirements/Specifications...

1. Your program run must be identical with the one shown as an example (both in how it reads the input and it on what it prints). The table must have the top and bottom lines as shown.
2. The columns for Last and First must have exactly 15 spaces each.
3. The data in the columns must be LEFT aligned
4. You can assume that the user gives good input: two words separated by one space.
