Does coffee or some other form of simulation really allow a person suffering from alcohol intoxificationto "sober up"? A sample of 44 healthy male students participated in the experiment. Each student wasasked to memorize a list of 40 words (20 words on a green list and 20 words on a red list). The studentswere then randomly assigned to one of four different treatment groups (11 students in each group).Students in three of the groups were each given two alcoholic beverages to drink prior to performing awork completion task. Students in Group A received only the alcoholic drinks. Participants in Group AChad caffeine powder dissolved in their drinks. Group AR participants received a monetary award forcorrect responses on the word completion task. Students in Group P (the placebo group) were told thatthey would receive alcohol, but instead received two drinks containing a carbonated beverage (with afew drops of alcohol on the surface to provide an alcoholic scent). After consuming their drinks andresting for 25 minutes, the students performed the word completion task. Their scores (simulated onthe basis of summary information from a certain article) are reported in the table. (Note: A task scorerepresents the difference between the proportion of correct responses on the green list of words andthe proportion of incorrect responses on the red list of words.)ARACA0.510.500.160.580.580.300.100.120.520.470.200.620.470.360.290.430.610.39-0.140.260.000.220.180.500.320.20-0.350.440.530.210.310.200.500.150.160.420.460.100.040.430.340.02-0.250.40Are there differences among the mean task scores for the four groups?

People with headaches are randomly divided into two groups. One group gets pain medication, and the other does not. One hour later, the participants are asked about their pain. Is it an experimental study or an observational study?
Ten new sales representatives for Clark Sprocket and Chain Inc. were required to attend a training program before being assigned to a regional sales office. At the end of the program, the representatives took a series of tests and the scores were ranked. For example, Arden had the lowest test score and is ranked 1; Arbuckle had the highest test score and is ranked 10. At the end of the first sales year, the representatives’ ranks based on test scores were paired with their first year sales.

Imagine I wanted to study the effectiveness of the Mediterranean diet on people’s memory. I tested a group of people who strictly followed the Mediterranean diet, another group who followed a typical Western diet, and another whose diet I did not change at all. Before the diet changes began, I gave all my participants a memory test. After six weeks of the diet experiment, I had all participants complete the same memory test again to see how scores would change among the three groups. For this study, identify a parameter and a statistic I might be interested in.
It’s that time of year again at Isaac’s Fireworks Store! New Year’s! Sale! Sale! Sale! However, Isaac is less than excited because last year he had a lot of complaints about a large number of defective fireworks that he sold. Isaac wants to know what percentage of his firework stock is defective. First, he plans to test his bottle rockets, so he takes a sample of 200 randomly chosen bottle rockets and he tests them. Of the 200, 14 failed. Construct a 80% confidence interval for the true proportion of bottle rockets that will fail.
For the three-part question that follows, provide your answer to each question in the given workspace. Identify each part with a coordinating response. Be sure to clearly label each part of your response as Part A, Part B, and Part C.Use the information below for Part A, Part B, and Part C. Every person at the park received a ticket. Of those tickets, only 45 were winning tickets. In a random sample of 25 people, 2 people had winning tickets.Part A: Write a ratio to represent the number of winning tickets to all tickets in the sample population.Part B: Make a reasonable claim or prediction about the population at the park.Part C: Justify your answer to Part B by showing your work.
Students in two elementary school classrooms were given two versions of the same test, but with the order of the questions arranged from easier to more difficult in version A and in reverse order in version B. Randomly selected students from each class were given version A and the rest given version B. The results are Version A:n1=31,x¯1=83,s1=4.6Version B:n2=32,x¯2=78,s2=4.3 Use a 0.01 significance level to test the claim that Version A is easier than version B.(Make sure you have the four steps shown similar to the examples that I gave) Assume that the two independent samples have been randomly selected from normally distributed populations. Instruction: 1) Must contains 4 steps as shown on the instructor's video. 2) Must identify whether the null hypothesis or the alternative hypothesis is the claim. 3) When doing the calculation, do not calculate standard error. 4) When finding the p-value, must show whether it is left-, right-, or two-tailed. 5) When drawing conclusion, must…
Dr. Moas is interested in examining how environmental cues affect memory. She asks 15 students to study 10 obscure words for a vocabulary exam. All students take the final vocabulary exam in Classroom A. She randomly assigns participants to one of three locations to study for the exam: the same classroom (Classroom A), a different classroom (Classroom B), or a completely separate location, the school gym. Then, she records the number of vocabulary words that each student correctly defines on the exam. The data is as follows: Participant Study Location Vocabulary Words Answered Correctly 1 Same Classroom 9 2 Same Classroom 8 3 Same Classroom 10 4 Same Classroom 8 5 Same Classroom 9 6 Different Classroom 9 7 Different Classroom 8 8 Different Classroom 7 9 Different Classroom 8 10 Different Classroom 7 11 School Gym 6 12 School Gym 7 13 School Gym 5 14 School Gym 6…

In a survey about people's relationship with their pets, one of the questions asked if the person felt guilty when they left their pets alone when they went on holidays. The response for each person was recorded as "Yes- feels guilty" or "No - does not feel guilty". The researchers were interested to see if men and women felt differently in this situation. Which of the following procedure is the most appropriate one to decide if the feeling of being guilty about leaving pets alone is different for men and women: A) Chi-squared test for independence B) Paired T-test C) Unpaired T-test D) Linear regression
