8.18 Virtual reality hypnosis for pain. The International Journal ofClinical and Experimental Hypnosis (Vol. 58, 2010) investi-gated using virtual reality hypnosis (VRH) to reduce the painof trauma patients. Patients reported their pain intensity onthe Graphic Rating Scale (GRS) both prior to and one hourafter a VRH session. The researchers reported that hypnosisreduced the pain intensity of trauma patients by an average ofµ = 10 points on the GRS. Suppose you want to test whethertrauma patients who receive normal analgesic care (i.e., medi-cation, but no hypnosis) will have a smaller reduction in aver-age pain intensity than the VRH trauma patients.a. Set up Ho and H, for the test.b. Describe a Type I error for this test.c. Describe a Type II error for this test.

The objective of the study is to test whether trauma patients who receive normal analgesic care will…

Studies show that the level of anxiety has changed since the pandemic. The average score before the pandemic was mu equal to 36. A sample of 20 individuals surveyed in the past two weeks produced M=37.6 and s=9.8. Based on the sample, was there a significant difference in the average anxiety level since the pandemic started at the 5% significance level? What is the positive critical value? (a)2.093 (b)2.086 (c)1.729 (d)1.725
People with chronic airflow obstruction are believed to have a limited exercise tolerance. This limited tolerance is thought to be mainly due to impaired ventilation mechanics. In a study designed to measure the effect (if any) that a new treatment had on the exercise capacities of individuals with chronic airflow obstruction, investigators measured, among other things, maximum exercise ventilation (VEmax) before and after the treatment was applied. The raw VEmax data are reproduced in the table below. The investigators would like to determine if there was an increase in the maximum exercise volume as a result of the treatment. Let ? = 0.025.

Your team members were interested in (a) how students were connecting with their professors and lecture content, (b) how in control students felt over their learning, and (c) how much they valued what they were learning during online lectures given the switch from in-person to virtual learning at the start of the pandemic. They collected data by briefly interrupting students at three-time points throughout an online lecture (similar to Dataset 1) to answer three different questions. They were asked “did you generate a personal connection with the information you were learning?” on a scale of 1 (not at all) to 9 (extremely), “I have the impression that my learning the content from this lecture so far has been under my control” on a scale from 1 (strongly disagree) to 5 (strongly agree), and “I believe that the content I learned from this lecture so far has been valuable for me to learn” on a scale from 1 (strongly disagree) to 5 (strongly agree). Each answer that participants provided…

Question The relationship between United States unemployment and inflation rates during the Covid-19 pandemic. Background The covid-19 pandemic has led to higher unemployment rates in the United States than normal because many people were laid off jobs in response to the pandemic (Al-Fadly, 2020). It is important to analyze how such as sharp increase in unemployment affected inflation in relation to how unemployment have traditionally affected inflation. The overall relationship between unemployment and inflation has traditionally been an inverse one. It is argued that when unemployment rates are higher, the number of individuals who are looking for jobs usually becomes higher than the number of job positions that are available (Putnam & Azzarello, 2015). In such a situation, employers tend to pay lower wages because there is abundance of workers which naturally leads to a lower wage inflation. This study will examine the relationship between unemployment rates and inflation…

widely used as dielectrics and coolants in electrical systems in the past. They were found to be a major environmental contaminant in the 1960s. In a study, the mean PCB content at each of thirteen sites was reported for the years 1982 and 1996 (from “The ratio of DDE to PCB concentrations in Great Lakes herring gull eggs and its use in interpreting contaminants data”, Journal of Great Lakes Research 24 (1): 12-31, 1998). The data are below.Site:12345678910111213198261.4864.4745.5059.7058.8175.9671.5738.0630.5139.7029.7866.8963.93199613.9918.2611.2810.0221.0017.3628.207.3012.809.4112.6316.8322.74(a) Which test would be more appropriate in this case: a t-test for the difference between two population means, or a paired t-test? Why?(b) Do the data provide sufficient evidence to support the claim that the mean PCB level has decreased in the region? Be sure to check all assumptions, write the null and alternative hypotheses, calculate the appropriate test statistic, calculate the p-value,…
