Using JAVA and NETBEANS

Assignment Content

1. For this assignment, you will develop "starter" code. After you finish, your code should access an existing text file that you have created, create an input stream, read the contents of the text file, sort and store the contents of the text file into an ArrayList, then write the sorted contents via an output stream to a separate output text file.

   Copy and paste the following Java™ code into a JAVA source file in NetBeans:

   import java.io.BufferedReader;

   import java.io.BufferedWriter;

   public class Datasort {

   public static void main (String [] args) {

   File fin =     // input file

   File fout =   // create an out file

   // Java FileInputStream class obtains input bytes from a file

   FileInputStream fis = new FileInputStream(fin);     

   // buffering characters so as to provide for the efficient reading of characters, arrays, and lines

   BufferedReader in = new BufferedReader(new InputStreamReader(fis));

   // declare an array in-line, ready for the sort

   String aLine;

   ArrayList<String> al = new ArrayList<String> ();

   int i = 0;

   while ((aLine = in.readLine()) != null) {

   // set the sort for values is greater than 0

   Collections.sort(al);   // sorted content to the output file

   {

   System.out.println(s);             

   }

   // close the 2 files                       

   }

   }

   Add code as indicated in the comments.

   Note: Refer to this week's Individual assignment, "Week Three Analyze Assignment," and to Ch. 8, "IO," in OCP: Oracle^® Certified Professional Java^® SE 8 Programmer II Study Guide.

   Run and debug your modified program in NetBeans until it satisfies the requirements described above.

Multiple myeloma, or blood plasma cancer, is characterized by increased blood vessel formulation (angiogenesis) in the bone marrow that is a predictive factor in survival. One treatment approach used for multiple myeloma is stem cell transplantation with the patient's own stem cells. The data show below represents the bone marrow microvessel density for patients who has a complete response to the stem cell transplant (as measured by blood and urine tests). The measurements were taken immediately prior to the stem cell transplant and at the time the complete response was determined. Patient Before After 1 158 284 2 186 214 3 202 101 4 353 227 5 416 290 6 426 176 7 441 290

(a) At the 0.05 level of significance, is there evidence that the mean bone marrow microvessel density is higher before the stem cell transplant than after the stem cell transplant? (Be sure to include the null and alternate hypotheses as well as the value of the test statistic. State the decision rule used and write you conclusion in a complete sentence.)

(b) Interpret the meaning of the p-value in (a).

(c) Construct and interpret a 95% confidence interval estimate of the mean difference in bone marrow microvessel density before and after the stem cell transplant.

(d) What assumption is necessary about the population distribution in order to perform the test in (a)?

The insulin pump is a device that delivers insulin to a diabetic patient at regular intervals. It presumably regulates insulin better that standard injections. However, data to establish this point are few, especially in children. The following study was set up to assess the effect of use of the insulin pump on HbgA1c, which is a long term marker of compliance with insulin protocol. In general, a normal range for HgbA1c is < 7%. Data were collected on 256 diabetic patients for 1 year before and after using the insulin pump. A subset of the data for 10 diabetic patients is given in the table below.

ID: HgbA1c i year before (%) HgbA1c 1 year after (%)

1. 6.7 7.0

2. 7.4 7.4

3. 9.2 8.6

4. 9.6 8.1

5. 7.4 6.8

6. 8.1 7.0

7. 10. 8 8.5

8. 7.1 7.7

9. 7.9 9.7

10. 10.8 7.7

Test the hypothesis that the measured HgbA1c 1 year after the insulin pump will be different from HgbA1c 1 year before thr insulin pump.Set your p - value to indicate statistical significance at ,0.05.

1. What is the null and alternative hypothesis

2. What is the means and standard deviation for each group

3. What is the alpha level, the df and whether it is one tail or two tail
