Each of the variables are described as follows.

Feelings towards Barack Obama are measured 0-100 with higher values indicating more positive opinions.

Gender is variable that equals 1 for respondents who identify as female and 0 for respondents who do not.

Race is a variable that equals 1 for respondents who identify as white and 0 for respondents who do not.

Age is the number of years the respondent reports having been alive.

Income is a 28-point scale with higher values denoting greater income earned.

Education is a four-point scale with higher values denoting greater educational attainment (High school or less, Some college, Finished college, Advanced degree).

Marital status is a variable that equals 1 for respondents who are married and 0 for respondents who are not.

Partisanship is the respondents’ self-placement on a seven-point scale ranging from 1 to 7 as follows: Strong Democrat, Weak Democrat, Democratic Leaning Independent, Independent, Republican Leaning Independent, Weak Republican, Strong Republican.

Write a Java program (name it InputSum) that prompts the user to enter positive integer numbers using a sentinel while loop. The program should accept integer inputs until the user enters the value -1 (negative one is the sentinel value that stops the while loop). After the user enters -1, the program should display the entered numbers followed by their sum as shown below. Notice that -1 is not part of the output. The program should ignore any other negative input and should continue to run.

Hint: to remember/save the entered (good) positive values, you can concatenate them into a string (separated by comas) that you can output later on.

The following are sample runs showing the input prompt and the outputs: (Notice the user may enter one value per line. DO NOT read inputs as String type)

Enter positive integers (-1 to quit): 10 -5 2 -1

Entered Numbers: 10, 2

The Sum: 12

Enter positive integers (-1 to quit): 1 2 3 4 5 6 -1

Entered Numbers: 1, 2, 3, 4, 5, 6

The Sum: 21

Enter positive integers (-1 to quit): 1 1 -7 1 1 -9 100 -1

Entered Numbers: 1, 1, 1, 1, 100

The Sum: 104

Make sure the program validates each entered number before processing it as the user may enter negative numbers (other than the sentinel value -1).

Design your program such that it allows the user to re-run the program with a different set of inputs in the same run.

Document your code, and organize and space out your outputs as shown above.

Write a class to implement HeadTailListInterface. Instead of using an array, use a List object as your instance data variable. (List (Links to an external site.) from the Java standard library- not ListInterface!). Instantiate the List object to type ArrayList.

Inside the methods of this class, invoke methods on the List object to accomplish the task. Note: some methods might look very simple... this does not mean they are wrong!

There is one difference in how this class will work compared to the other: in this extra credit class, you do not have control over the capacity, so you should not print the capacity in display and the capacity does not have to be exactly doubled in the two add methods.

For full credit:

  • Pay close attention to what should happen in "failed" conditions as described by the HeadTailListInterface compared to List!
  • Make sure your ListHeadTailList behaves as described in HeadTailListInterface.
  • Use the methods of the List interface/ArrayList class when possible instead of re-writing the code yourself.

The class header and instance data will be:

List<T> list; // initialize to type ArrayList<T> in the ListHeadTailList constructor

As part of a study on stress and its effects on aging, researchers measured telomere length in blood cells of healthy premenopausal women with chronically ill children.

Here is a link to the data.

Question: What is the correlation coefficient for these variables? Calculate your answer using the function =correl(array 1, array2) in microsoft excel. Answer to three decimal places.

B. Based on your calculated correlation coefficient, how would you describe the correlation between the length of telomeres and and the number of years healthy pre-menopausall woman cared for chronically ill children?

strong negative

weak negative

weak positive

strong positive

no correlation

C. Based on the correlation between telomere and caring for chronically ill children, how would you expect stress to impact aging?

Increased stress increases the rate of aging, as seen by shorter telomeres.

Increased stress increases the rate of aging, as seen by longer telomeres.

Increased stress decreases the rate of aging, as seen by shorter telomeres.

The absence of a correlation between telomeric length and carying for a chronically ill child suggests that stress does not impact aging.

You must program the game called MaDi which is described below. There is a board of NxN (the size N is defined by the user and must be a number greater than or equal to 2), where in each box there is an instruction. The first (the [0] [0]) and the last box (the [N-1] [N-1]) have no instruction. Possible instructions are:
1. Don't move
2. Advance 4 places
3. Jump to the next row
4. Go back 2 places
5. It exploded! End of the game.
In order to facilitate the visualization of the matrix for the player, the instruction number will be displayed on the board and below it the list of instructions with their numbering.
Instructions:
1. Don't move
2. Advance 4 places
3. Jump to the next row
4. Go back 2 places
5. Bomb! Exploded.
The instruction that goes in each square of the board will be assigned randomly each time the game starts.
The player starts with his chip in the first position (row: 0, column: 0) and (bottom-right corner). On each turn the player rolls a die that will tell him how many spaces to advance. You advance across the board from left to right and from top to bottom as follows:
On each turn the player rolls a dice that tells him how many positions on the board to advance. After advancing, he must execute what is indicated in the instruction of the box where he fell. For each turn, only execute one instruction on the board. The player has a maximum number of rolls of the dice, which will be asked to the player when starting the game.
The game is lost if the dice are thrown without having reached the goal or if the product of rolling the dice advances to a square with a bomb. The game is won if you reach the goal (it does not have to be by exact count) before the roll of the dice runs out.

Lester Hollar is vice president for human resources for a large manufacturing company. In recent years, he has noticed an increase in absenteeism, which he thinks is related to the general health of the employees. Four years ago, in an attempt to improve the situation, he began a fitness program in which employees exercise during their lunch hour. To evaluate the program, he selected a random sample of eight participants and found the number of days each was absent in the six months before the exercise program began and in the last six months. Below are the results.

Employee Before After
1 1 5
2 2 6
3 5 4
4 6 7
5 4 1
6 7 3
7 6 5
8 4 3

At the .05 significance level, can he conclude that the number of absences has declined? Estimate the p-value.

a. State the decision rule for 0.1 significance level: H0 : μd≤ 0; H1 : μd > 0. (Round the final answer to 3 decimal places.)

Reject H0 if t > ???

b. Compute the value of the test statistic. (Round the final answer to 3 decimal places.)

Value of the test statistic ???   

c. Estimate the p-value? (Round the final answer to 4 decimal places.)

???
