- When playing the game of rock, paper, and scissors. I want to create a chi-square test regarding if the null hypothesis is people favor rock over other components, and the alternative hypothesis would be outcomes aren't favored because people's preferences change during the game. How would I make a chi-square and convert it into a chart or graph with this information below? The results so far are two people who played four games. Round one score is 0:3player 1: paper, paper, rock player 2 (opponent) scissors, scissors, paper (winner) -----Round two score is 1:3 Player 1: scissors, paper, rock, scissors, paper, rock, scissors Player 2: rock, paper, rock, scissors, rock, paper, rock (winner) ----Round three score is 3:2 Player 1: rock, scissors, rock, paper, paper, rock, paper, rock (winner) Player 2: rock, scissors, scissors, scissors, paper, rock, scissors, scissors----- The final round 4 score is 3:2Player 1: paper, scissors, rock, scissors, paper, rock (winner) Player 2: rock, paper,…NEW STUDY: Dr. Apnea conducted a study investigating the effects of sleep deprivation on complex problem solving. He gave 25 college students a problem-solving test at noon on one day and a second problem-solving test at noon the following day. He found that there was a statistically significant mean decrease of 4.7 between the two tests from the first day to the second day. The test yielded a Cohen’s d = .82. Which of the following statements is an accurate interpretation of Dr. Apnea’s research? Group of answer choices It doesn’t matter how much sleep you get, some people just aren’t good at problem solving. If you don’t get enough sleep your problem solving abilities suffer, but only with a small absolute magnitude. If you don’t get enough sleep your problem solving abilities suffer with a medium absolute magnitude. If you don’t get enough sleep your problem solving abilities suffer with a large absolute magnitude.2

A report looked at the median hourly wage gain per additional year of schooling in 2007. The report states that workers with a high school diploma had a median hourly wage that was 13% higher than those who had only completed 11 years of school. Workers who had completed 1 year of college (13 years of education) had a median hourly wage that was 14% higher than that of the workers who had completed only 12 years of school. The added gain in median hourly wage for each additional year of school is shown in the accompanying table. The entry for 15 years of schooling has been intentionally omitted from the table.

- Claim: Most adults would erase all of their personal information online if they could. A software firm survey of 678 randomly selected adults showed that 50.5% of them would erase all of their personal information online if they could. Make a subjective estimate to decide whether the results are significantly low or significantly high, then state a conclusion about the original claim. The results v significantly v so there V sufficient evidence to support the claim that most adults would erase all of their personal information online if they could.Compare What-If Analysis using Trial and Error and Goal Seek to the given scenario: Let's say a student is enrolled in an online class at a learning institution for a semester. His overall average grade stands at 43% in the course (Term Grade is 45%, Midterm Grade is 65%, Class Participation is 62% and Final Exam is 0%). Unfortunately, he missed his Final Exam and was given 0%. However, he has the opportunity to redo his Final Exam and needs at least an overall average of 60% to pass the course. How can you use Trial and Error and Goal Seek to find out what is the lowest grade he needs on the Final Exam to pass the class? Which method worked best for you and why?WebAssign + → X CO TE ICTTET EER .... .... ...... H...... How profitable are different sectors of the stock market? One way to answer such a question is to examine profit as a percentage of stockholder equity. A random sample of 26 retail stocks such as Toys 'R' Us, Best Buy, and Gap was studied for x1, profit as a percentage of stockholder equity. The result was x1 = 13.6. A random sample of 33 utility (gas and electric) stocks such as Boston Edison, Wisconsin Energy, and Texas Utilities was studied for x2, profit as a percentage of stockholder equity. The result was x2 = 10.1. Assume that o1 = 4.2 and o, = 3.3.

- Need part CReview of Independent t-test Base your answers on the following problem and data. A student researcher wants to test the hypothesis that students who are made to feel anxious by a critical teacher cannot learn math concepts as well as students who are assigned to a supportive teacher. For the student's 301 project, the student recruits 14 participants and randomly assigns the participants to learn new math concepts from either a critical (n=7) or supportive teacher (n=7). All other variables are kept the same; in fact, a single person performs the roles of both the supportive and critical teacher, but just modifies her behavior accordingly. Each group of participants then takes a test after the math lesson and their scores on the test are measured. Here is the resulting data: Critical Teacher 27 25 19 10 16 22 14 Supportive Teacher 25 29 18 23 20 15 19RABCD X₁ 12 20 2 A researcher is interested in seeing if listening to a political debate changes anxiety scores among people. The researcher knows of no previous research that would predict whether anxiety scores would be raised or lowered.
