A visiting comparative literature student from Cambridge University believes that contemporary readers prefer novels from George RR Martin (the author of the Games of Thrones saga) to Shakespeare. She devises a study in which 40 participants are asked to read excerpts from both Shakespeare plays and Games of Thrones books and rate their level of satisfaction for each excerpt. Satisfaction is measured using a 5-point Likert scale (5 indicates high satisfaction). In order to allow for a fair comparison, she hides the name of the authors and recruits a professional translator to adapt the Games of Thrones text to old Elizabethan English. The order of presentation is also randomised and balanced across participants. The attached CSV file contains the data that was collected for the experiment. What can you conclude from the results of this experiment? I require assistance on: Identifying the appropriate statistical test. Conducting the statistical test in JASP, Excel or SPSS. Reporting…
The work week for adults in the US that work full time is normally distributed with a mean of 47 hours. A newly hired engineer at a start-up company believes that employees at start-up companies work more on average then most working adults in the US. She asks 12 engineering friends at start-ups for the lengths in hours of their work week. Their responses are shown in the table below. Test the claim using a 10% level of significance. Hours 47 47 55 51 48 65 51 52 50 49 51 54 What are the correct hypotheses? Ho: Select an answer ✓ ? ✓ Ha: Select an answer ✓ Test Statistic= hours Based on the hypotheses, find the following: p-value= hours (Give answer to at least 4 decimal places.) (Give answer to at least 4 decimal places).
Q3.3 Normal, but why? A meal package for use at the space station is to be prepared by combining three separate components: protein, fruit/vegetable, and grains. Each of the components is to be randomly selected. Summary values for the caloric content for each of the components are given in the table. Component Protein (P) Fruit/vegetable (F) Grain (G) Mean (calories) 120 55 84 Stdv (calories) 6.4 Save Answer 1.0 3.6 Assume that the distributions of caloric content for each of the components are approximately normally distributed. Since the meal package consists of protein, fruit/vegetable, and grains, the total caloric content of a meal package is the random variable T, where T = P + F + G. Briefly explain why it is appropriate to say that T is approximately normally distributed. Q3.4 Probability Less than 275 Calories On your own piece of paper find the approximate probability that a randomly selected meal package will have less than 269 calories? (Draw an appropriate diagram, find a…
2. The following exercises are based on a study by Scholer et el. (1997). This was a nested case-control study obtained from a cohort of children age 0 through 4 years in Tennessee between January 1, 1991 and December 31, 1995. Case patients consist of all cohort members who suffered injury deaths. Control patients were frequency matched to case patients by birth year. The variables are; Pnclate Byear injflag byear 986 987 988 989 990 991 993 994 995 Crude M-H combined Illegit OR = 1.366071 1.171363 3.292431 2.18427 2.561502 2.484556 2.431203 2.900458 1.894737 2.256993 2.279816 Test of homogeneity (M-H) year of birth 1: a.

The results of IKEA's Annual Job Satisfaction Survey showed that 30% of employees are very satisfied with their job, 46% are satisfied, 20% are dissatisfied, and 4% are very dissatisfied. A sample of 50 managers yielded the following results: Category Very satisfied Satisfied Dissatisfied Very dissatisfied Number of Respondents 15 20 10 5 Test using a = 1% to determine whether the job satisfaction for employees is different from the job satisfaction for managers.
To study how well rats can learn, behavioral scientists used a sample of rats in a maze experiment. Each rat had to find itway through a maze to reach a treat at the end. The rat was timed on its first trial run and again on its tenth eighth trial run. The difference in the times was recorded for each rat. Which of the following is the most appropriate procedure for the scientists to use? A- A matched pair t-interval for a mean diffderence B- A two sample t interval for a difference between means C- a one sample t interval for a sample difference D-A one sample z interval for a population proportion E- A two sample z interval for a difference between proportions
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 ______.
