- Two separate samples receive two different treatments. The first treatment group (N = 9) has a mean of 50 with SS = 710. The second treatment group (N = 6) has a mean of 60 with SS = 460. Is the second treatment group significantly larger than the first? What is the effect size?can you explain how these scores were found, based on the statistics provided they dont seem to match up.' There is a significant interaction effect between employment status and substance use on stress levels. Two-Way ANOVA result: F(3,470) = 5.67, p = 0.001' IOxyContin is a drug used to treat pain, but it is well know for its addictiveness and danger. In a critical trial, among subjects treated with OxyContin, 52 developed nausea and 175 did not. Among other subjects given placebos, 5 developed nausea and 40 did not. Use a 0.05 significance level to test for a difference between the rates of nausea for those treated with Oxycontin and those given a placebo! Question: state the conclusion
- Consider a drug that is used to help prevent blood clots in certain patients. In clinical trials, among 6225 patients treated with this drug, 164 developed the adverse reaction of nausea. Use a 0.01 significance level to test the claim that 3% of users develop nausea. Does nausea appear to be a problematic adverse reaction? OC. Ho:p= 0.03 H4:p>0.03 O D. Ho: p#0.03 H:p=0.03 Identify the test statistic for this hypothesis test. The test statistic for this hypothesis test is (Round to two decimal places as needed.) Identify the P-value for this hypothesis test. The P-value for this hypothesis test is. (Round to three decimal places as needed.) Identify the conclusion for this hypothesis test. O A. Reject Hn. There is sufficient evidence to warrant rejection of the claim that 3% of users develop nausea. O B. Reject Ho. There is not sufficient evidence to warrant rejection of the claim that 3% of users develop nausea. OC. Fail to reject Ho. There is sufficient evidence to warrant rejection…In one study of smokers who tried to quit smoking with nicotine patch therapy, 38 were smoking one year after treatment and 33 were not smoking one year after the treatment. Use a 0.01 significance level to test the claim that among smokers who try to quit with nicotine patch therapy, the majority are smoking one year after the treatment. Do these results suggest that the nicotine patch therapy is not effective? Null and alternative hypotheses for this test. H0 : p=0.5 / H1 : p>0.5 A) Identify the test statistic for this hypothesis test. B) Identify the P-value for this hypothesis test.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 psychologist wanted to study the effect of television violence on cortisol levels in the blood (high scores indicate high levels). The psychologist measured cortisol levels in seven participants before and after the participants watched a violent show. Participants' cortisol level scores are listed below. The researcher is interested if there is a change in the cortisol levels after watching the violent show. Carry out a t test for dependent means (using the .01 significance level). What should the researcher conclude? a.) Use the five steps of hypothesis testing. Label all the steps clearly. Show ALL work/calculations. b.) Report the statistic in APA format (the statistical sentence).

Does sustain care appear to be effective. m. What is Type 2 error? Explain its consequence in the context…A new method was developed to reduce variability of test scores by eliminating lower scores. Two groups, one called the control group and the other, the experimental group, both took the same test. The experimental group was taught using the new method. Do the data provide sufficient evidence to conclude that there is less variation among scores when the new method is used? Perform an F-test at the 1% significance level.
