In large corporations, an "intimidator" is an employee who tries to stop communication, sometimes sabotages others, and, above all, likes to listen to him or herself talk. Let x1 be a random variable representing productive hours per week lost by peer employees of an intimidator. x1: 7 2 7 3 2 5 2 A "stressor" is an employee with a hot temper that leads to unproductive tantrums in corporate society. Let x2 be a random variable representing productive hours per week lost by peer employees of a stressor. x2: 2 2 10 8 6 2 5 8 (i) Use a calculator with sample mean and sample standard deviation keys to calculate x1, s1, x2, and s2. (Round your answers to two decimal places.) x1 = s1 = x2 = s2 = (ii) Assuming the variables x1 and x2 are independent, do the data indicate that the population mean time lost due to stressors is greater than the population mean time lost due to intimidators? Use a 5% level of significance. (Assume the population distributions of time lost due to intimidators and time lost due to stressors are each mound-shaped and symmetric.) (a) What is the level of significance? State the null and alternate hypotheses. H0: μ1 < μ2; H1: μ1 = μ2 H0: μ1 = μ2; H1: μ1 ≠ μ2 H0: μ1 = μ2; H1: μ1 < μ2 H0: μ1 = μ2; H1: μ1 > μ2 (b) What sampling distribution will you use? What assumptions are you making? The Student's t.

Are the data statistically significant at level α? At the α = 0.05 level, we reject the null hypothesis and conclude the data are not statistically significant. At the α = 0.05 level, we fail to reject the null hypothesis and conclude the data are statistically significant. At the α = 0.05 level, we reject the null hypothesis and conclude the data are statistically significant. At the α = 0.05 level, we fail to reject the null hypothesis and conclude the data are not statistically significant. (e) Interpret your conclusion in the context of the application. Fail to reject the null hypothesis, there is sufficient evidence that the mean time lost due to stressors is greater than the mean time lost due to intimidators. Reject the null hypothesis, there is insufficient evidence that the mean time lost due to stressors is greater than the mean time lost due to intimidators. Fail to reject the null hypothesis, there is insufficient evidence that the mean time lost due to stressors is greater than the mean time lost due to intimidators. Reject the null hypothesis, there is sufficient evidence that the mean time lost due to stressors is greater than the mean time lost due to intimidators.

Write a Java program to play the game Tic-Tac-Toe. Start off with a human playing a human, so each player makes their own moves.

Follow the design below, creating the methods indicated and invoking them in the main program.

Use a char array of size 9 as the board; initialize with the characters 0 to 8 so that it starts out looking something like the board on the left.

Make sure the board lines up properly so that the entries and borders all line up properly. DO NOT print a board that looks like or is similar to the output below where columns are misaligned.

0| O|2

3|X | 5

6 | X|O

You will need a variable to keep track of whose turn it is. Use a char variable named turn and initialize to X when the game starts. After a move, if there is no winner and no draw, switch to the O and continue to take turns as the game progresses. Declare additional variables as you build your program.

1. After the variable declarations, begin a while loop which will keep the game going the user indicates to stop the game. (see a. below)
   1. When a new games starts, allow the user to terminate the program by entering an S or s (remember String has toLowerCase and toUpperCase methods). Any other entry will start a new game.
2. If you are starting a new game, invoke a method to initialize the board and turn and another method to print the board
3. Start an inner while loop that runs as long as the game isn’t over (a win or draw will terminate the game but not the program).
4. Invoke a method to allow the user to make a move
   1. If there is no empty spot, (the game is a draw), print a message and ask the user whether to start a new game or terminate the program
   2. If the value entered is invalid (not 0 to 8), print a message and allow the user to re-enter a move
   3. If the user enters a value but it’s already taken, print a message and allow the user to retry
   4. If the user enters a value and it’s available, set the spot to X or O (depending upon the value of turn) and print the board
5. After a valid move is made, invoke a method to check if the last one to make a move won the game
   • Winner - print the winner and start a new game
   • No winner - switch turn and ask for the next position

SAMPLE OUTPUT – NOTE OUTPUT BOLDED TO SHOW HANDLING OF BAD ENTRIES

The following is a small data set of 25 observations. I want you to calculate some statistics by hand to cement the class material. You can use the regular formula for the variance or the computational formula - I’m just interested in the correct result. If you use the computational formula, you will want to calculate a separate row of each value squared in order to calculate the Sum(x^2). Excel can be used to solve this problem.

1. Create a Stem and Leaf Plot of the data (it is easy to do in Word by making a two column table and entering the numbers in there, bolding the stems)

b. Calculate the following (show your work):

• Mean
  • Median
  • Mode
  • Range
  • Variance
  • Std. Deviation
  • Coefficient of Variation

c. Calculate a z-score for a data value of 46. Describe this in words.

Write a loop that sets each array element to the sum of itself and the next element, except for the last element which stays the same. Be careful not to index beyond the last element. Ex:

Initial scores:        10, 20, 30, 40
Scores after the loop: 30, 50, 70, 40

The first element is 30 or 10 + 20, the second element is 50 or 20 + 30, and the third element is 70 or 30 + 40. The last element remains the same.

JAVA CODE:

import java.util.Scanner;
public class StudentScores {
public static void main (String [] args) {
Scanner scnr = new Scanner(System.in);
final int SCORES_SIZE = 4;
int[] bonusScores = new int[SCORES_SIZE];
int i;

for (i = 0; i < bonusScores.length; ++i) {
bonusScores[i] = scnr.nextInt();
}

/* Your solution goes here */

for (i = 0; i < bonusScores.length; ++i) {
System.out.print(bonusScores[i] + " ");
}
System.out.println();
}

A researcher interested in the treatment of depression developed an intensive treatment program designed to teach people to think positively. The researcher began the study by recruiting 50 college students who received extremely low scores on a well-validated measure of self-esteem. Each of the 50 participants agreed to attend four 1-hour therapy sessions per week for two weeks (for a total of eight sessions). Thirty-seven of the 50 original participants remained in the study and completed all eight sessions. At the end of the 2-week period of the study, the mean self-esteem score for the 37 participants who received all of the therapy showed a large and statistically significant increase. The researcher concluded that his program is an effective treatment for depression.

Name at least four issues with this study and explain why.

IGM Financial has paid a dividend of $2.25 per year for the last five years, however, due to COVID, investors think dividends will be reduced. Investors think dividends for the next two years will be $1 and will then resume at $2.25 per year and will grow at 2% indefinitely after that. If investors are right, what is the value of a share of IGM? Assume a discount rate of 7%.

Select one: a. $37.05 b. $41.11 c. $45.00 d. $47.00
