Experimental hypothesis in words?5. Which statistical analysis should be used and why? Problem B - Trauma victims frequently suffer from intrusive memories and images of thetraumatic event. The investigators are interested in the effectiveness of a new therapeutictechnique that uses structured recall of the traumatic event in conjunction with a cognitiverestructuring of the experience. We have seven trauma patients record their intrusive thoughts fora 1-week period before receiving the therapy (0 months), after 2 months of therapy (2 months), attermination (4 months), and again 2 months after completing therapy (6 months).

A researcher gathered a sample of participants who volunteered for a studying of phobias. She measured anxiety level of participants as they viewed photos of spiders and again when they viewed puppies. Which statistical test is appropriate for this study and why?
Researchers investigate how the presence of cell phones influence the quality of human interaction. Subjects are randomly selected from a population and divided into an experimental group that is asked to leave their phones in the front of the room and a control group that are not asked to leave their cell phones at the front of the room. Subjects are left alone for 10 minutes and then asked to take a survey designed to measure quality of interactions they had with others in the experiment. What statistical test is appropriate?
. A researcher suspects that the actual prevalence of generalized anxiety among children and adolescents is higher than the previously reported prevalence of generalized anxiety disorder among children and adolescents. The previously reported prevalence of generalized anxiety disorder among children and adolescents is 4.1%, and the researcher conducts a study to test the accuracy of the previously reported prevalence of generalized anxiety disorder by recruiting 98 children and adolescents from various pediatricians’ offices and tests them for generalized anxiety disorder using the DSM-5. The researcher determines that the prevalence of generalized anxiety disorder among the participants of the study is 6.8%. The researcher’s hypothesis, for a level of significance of 5%, should resemble which of the following sets of hypothesis? A) H0: p > .041; H1: p = .041; alpha= .05 B) H0: p > .041; H1: p = .041; alpha= .95 C) H0: p = .041; H1: p > .041; alpha= .05 D) H0: p = .041; H1: p…

Mammography and clinical breast examination are the two major techniques used to screen for breast cancer. However, as true for any screening test, they are not completely accurate. If it is determined, based on mammographic findings, that there is a possibility of breast cancer, this is usually confirmed or disconfirmed by a subsequent biopsy. A false positive test is a mammogram positive test that is disconfirmed by biopsy. The data in Table 1 were reported in a paper concerning breast cancer screening (Elmore, et al, New England Journal of Medicine 1998; 338(16): 1089-1096). Table 1 False positive breast cancer screening tests over a 10-year period # Screening tests # False positive tests 9762 631 1. Suppose 10 women are given mammograms. What is the probability that at least 1 woman will have a false positive test?
A research team is interested in the effect of the Parent Child Interaction Therapy (PCIT) in reducing children’s disruptive behaviors for children with disruptive behavior disorders (DBD). The research team recruited 12 families with child with DBD and interviewed the parents about the number of the disruptive behaviors the child has at home. After 3 weeks’ therapy, the research interviewed again about child’s disruptive behaviors. The disruptive before and after the therapy is list below. Test the researcher’s hypothesis at a 0.05 significant level. List 4 steps.

A new drug to treat psoriasis has been developed and is in clinical testing. Assume that those individuals given the drug are examined before receiving the treatment and then again after receiving the treatment to determine if there was a change in their symptom status. If the initial results showed that 2.0% of individuals entered the study in remission, 77.0% of individuals entered the study with mild symptoms, 16.0% of individuals entered the study with moderate symptoms, and 5.0% entered the study with severe symptoms calculate and interpret a chi-squared test to determine if the drug was effective treating psoriasis given the information below from the final examination. A. We reject H0 because 6628.08 is greater than 11.07. We have statistically significant evidence at the alpha equals .05 level to show that the distribution of the severity of psoriasis cases at the end of the clinical trial for the sample is different from the distribution of the severity of psoriasis…
Professor Chase from the University of Kansas has been working on a new cholesterol medication that is being called CholestoCleaner. The university is now conducting studies to determine if there is a possible side effect of sore joints. Placebo (Population Rate) To help determine the usual rate of sore joints, the research team gave a placebo (sugar pill) to 2017 subjects. Of those 2017 subjects, 4 of them developed sore joints. CholestoCleaner Trial The CholestoCleaner drug was given to 2622 subjects. Of those 2622 subjects, 19 of them developed sore joints. Preliminary Math If we consider the general population of people that don't use CholestoCleaner, what is the probability that they will develop sore joints? (Enter your answer as a fraction.) If you had a sample size of 2622 that did NOT use CholestoCleaner, how many would expect to develop sore joints? When 2622 subjects DID use the drug, there were 19 subjects that developed sore joints. Does it seem as though sore joints…
