Answer the questions below using the appropriate statistical technique. For questions involving the use of hypothesis testing, you must:
1. State the null and research hypotheses
2. Provide the Z(critical), T(critical), or χ 2 (critical) score corresponding to the α threshold for your test
3. Provide your test statistic
4. Provide your decision about statistical significance
An advantage that often comes with a basic knowledge of statistics is a change in salary. To see whether this was the case for Tulane University graduates, you took a random sample of 57 students who completed a statistics class and asked about their starting salaries (in thousands) after graduation. The sample had a mean of 53.3 with a standard deviation of 3.72 (i.e., x = 53.3 and s = 3.72). A call to the Office of the Registrar indicates that the average starting salary value for all Tulane students is 47.1. Do students who take statistics courses earn an equal salary compared to Tulane students generally? Use α = 0.001.

P1. Determine net income in 2013, 2014 and 2015. (Show work clearly)
P2. Determine basic earnings per share in 2013, 2014 and 2015. (Show work clearly)
P3. Determine comprehensive income in 2013, 2014 and 2015. (Show work clearly)
P4. Determine the balance of retained earnings at the end of 2015. (Show work clearly)
P5. Determine the balance of common stock at the end of 2015. (Show work clearly)
P6. Determine the balance of accumulated other comprehensive income at the end of 2015. (Show work clearly)
Hint : Use Equity = CS +RE+AOCI, along with A = L + E. No preferred stock (thus no preferred div, net income to common stockholders = net income)

Consider the following variant of the Interval Scheduling problem. There are n jobs and each job has a start time si and an end time fi . There is a single machine that can run at most one job at any given time. The jobs are now daily jobs. Once accepted, it must run continuously every day between its start and end times. (Note that a job can start before midnight and end after midnight.)
a) Design an algorithm that accepts as many jobs as possible. Your algorithm should run in time O(n 2 ) and output an optimal schedule (a set of intervals).
b) Prove the correctness of your algorithm and analyze its running time.
Example: Suppose there are 4 jobs, specified by (start-time, end-time) pairs: (9pm, 3am), (6pm, 6am), (3am, 1pm), and (2pm, 7pm). The optimal solution would be to pick 3 jobs (9pm, 3am), (3am, 1pm), and (2pm, 7pm), which can be scheduled without overlapping. (Hint: first enumerate an interval Ij = 1, . . . , n. How could we compute a schedule Oj with maximum size among all valid schedules that contain Ij?)

Professor Fair believes that extra time does not improve grades on exams. He randomly divided a group of 300 students into two groups and gave them all the same test. One group had exactly 1 hour in which to finish the test, and the other group could stay as long as desired. The results are shown in the following table. Test at the 0.01 level of significance that time to complete a test and test results are independent.
| Time | A | B | C | F | Row Total |
| 1 h | 22 | 43 | 61 | 13 | 139 |
| Unlimited | 18 | 47 | 80 | 16 | 161 |
| Column Total | 40 | 90 | 141 | 29 | 300 |

Exercise 1:
You are required to re-write the following code to catch the exception that can occur.
import java.util.Scanner;
public class ExceptionDemo
{
public static void main(String[] args)
{
Scanner scanner = new Scanner(System.in);
System.out.print("Enter an integer: ");
int number = scanner.nextInt();
// Display the result
System.out.println( "The number entered is " + number);
}
}

Exercise 2:
Try-Catch Exercise
Write a Java code that does the following:
Create a class MyClass and create three methods myMethod1(), Method2() and Method3().
Invoke Method2() from Method1() and Method3() from Method2().
Write a code that can throw an exception inside myMethod3() and compile:
File file=new File("filename.txt");
Scanner sc=new Scanner(file);
You will get compilation errors now, as you are not handling a checked exception FileNotFoundException.
Declare throws over myMethod3() and myMethod2(). You will need to add throws FileNotFoundException on myMethod() as:
public void myMethod3() throws FileNotFoundException
{
File file=new File("filename.txt");
Scanner sc=new Scanner(file);
}
Handle the exception in myMethod1() by enclosing the code that can throw exception using a try-catch block:
public void myMethod1()
{
try{
myMethod2();
}
catch(FileNotFoundException e)
{
e.printStackTrace();
}
}
