A survey asks 1200 workers, "Has the economy forced you to reduce the amount of vacation you plan to take this year?" Thirty-three percent of those surveyed saythey are reducing the amount of vacation. Twenty workers participating in the survey are randomly selected.

You are doing research on balance and fitness. To complete this research you will need a watch with a second hand. Identify a random sample of n = 12 men and n = 8 women. You must answer this question: How do you establish that this sample is truly random? Have each subject perform the following task: Have the subjects stand with their hands at their side, raise one knee, cross their ankle over the other knee, squat and bring their hands palms together in front of their chest. Time the subject until they put their foot back down on the floor. b) Ask the following questions: i) How many days per week do they exercise? ii) What is their favorite exercise? You will analyze your data and compute the following statistics for each group: 1) The Mean and standard deviation of the number of seconds the subject stayed balanced 2) The Median number of days per week exercised 3) The Mode of the favorite exercise 4) The 90% confidence interval of the mean Construct a complete…
Textbook question for practise - A behavioural psychologist has developed a cognitive-behavioural therapy (CBT) technique modified from classic systematic desensitization to reduce her patients’ phobia of spiders. She decides to test the effectiveness of her new therapy approach by selecting ten patients at random to undergo the treatment for 3 months. The patients were asked to rate how much fear they feel/experience when in the presence of a spider/spiders using a scale from 0 (no fear at all) to 100 (extreme panic and fear). They were tested before and after the therapy. The ratings for each patient are as follows: For this question, be sure to do the following: ▪ State the statistical hypotheses (using the appropriate notation). ▪ Indicate whether the research hypothesis is non-directional or directional (and how you know). ▪ Set the decision rules, which will include: o State alpha - 0.05% o Compute the degrees of freedom o Providing the critical value for the test statistic…
Dataset: NES. Variables: spend8, nesw.) The NES dataset contains spend8, which records the number of government policy areas where respondents think spending should be increased. Scores range from 0 (the respondent does not want to increase spending on any of the policies) to 8 (the respondent wants to increase spending on all eight policies). The NES, of course, polls a random sample of U.S. adults. In this exercise you will analyze spend8 using the Analyze ▶ Compare Means ▶ One-Sample T Test procedure. You then will draw inferences about the population mean. Make sure you weight observations using the nesw variable so your results are nationally representative. A. The spend8 variable has a sample mean of ______.

Scenario: A researcher wants to know whether a hard copy of a textbook provides additional benefits over an e-book. She conducts a study where participants are randomly assigned to read a passage either on a piece of paper or on a computer screen. After a distractor task lasting 30 minutes, the participants are tested for their comprehension of the passage with a multiple-choice test containing 10 questions about their passage. Comprehension was scored using percent correct (0 — 100%). The researcher predicts that those randomly assigned to read the passage on a piece of paper will remember significantly more than those who read the passage online. Question: What is the research / alternate hypothesis for this scenario? People who read a passage on a piece of paper will remember more than those who read a passage online. People who read a passage on a piece of paper will not remember more than those who read a passage online. Amount remembered of a passage will vary based…
