- please answer the following question thank youCardiovascular disease is a major cause of death and illness worldwide, with high blood pressure and high LDL cholesterol both being established risk factors. Because most cardiovascular events occur in persons with average risk and no previous cardiovascular disease history, the present research examined the simultaneous use of both blood pressure‑reducing drugs and cholesterol‑reducing drugs on this population rather than focus on only those at high risk. Subjects included men at least 55 years old and women at least 65 years old without cardiovascular disease who had at least one additional risk factor besides age, such as recent or current smoking, hypertension, or family history of premature coronary heart disease. Those with current cardiovascular disease were excluded from the study. Subjects were randomly assigned to the treatment (cholesterol‑ and blood pressure‑reducing drugs) or a placebo, and the number suffering the primary outcome of a fatal cardiovascular event or a…A local teacher wants to see if teaching writing in different ways impacts student learning. She has two classes of similar characteristics. In one class, she will use Teaching Strategy A and in the other class she will use Teaching Strategy B. She ran her analysis in Microsoft Excel and received the following output table. If the P value is less than 0.05, the null hypothesis may be rejected. Based on the data table, what decision should the teacher make about the hypothesis?
- A research team is interested in the effect of 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 a child with DBD and interviewed the parents about the number of disruptive behaviors the child has at home. After three weeks' therapy, the research interviewed again about the child's disruptive behaviors. What is the research question? What is/are the variable(s)? Are they categorical or continual variables? What statistical test can be used to answer the research question?Was the study an experiment (see Chapter 11) or quasi-experiment (see Chapter 12)? How do you know? Levine, L. J., Burgess, S. L., & Laney, C. (2008). Effects of discrete emotions on young children’s suggestibility. Developmental Psychology, 44, 681–694. Purpose of the Study. Levine, Burgess, and Laney (2008) conducted a study to investigate the effect of children’s emotions on their memory abilities and the likelihood that their memory accuracy would decline due to leading questions about their memories for a story. This knowledge may be useful in determining the conditions under which children’s memories are less likely to be accurate, which is important in various applied situations, such as when children must testify in court about something they experienced. Method of the Study. Four- and six-year-old children participated in the study. Each child was presented with three stories. A task at the end of each story was designed to elicit happiness, sadness, or anger. This…Explain why blinding is a reasonable strategy in many experiments. O Blinding helps researchers study the control effect better, since knowing if you are in the control group can have a mental effect on results. O Blinding can help solve the doubling issue in research, where people feel they need to match those around them in response/measurement. O Blinding keeps people and researchers from deliberately skewing the effects of the experiment, or to highlight a placebo effect. O Blinding can help solve the singling issue in research, where people feel they need to be unique from those around them in response/measurement.
- Since this research focuses on sleep habits in college students and its effect on mental health, we have proposed the research question to be what the prevalence of college student's mental health issues are due to poor sleeping habits.Previous research has shown that anxiety and depression can be two indicators of poor sleep habits in college students (Becker et al., 2018). As mentioned before, college students are also at risk of developing poor sleep habits because, as freshmen, they transition into a more significant workload than they are accustomed to doing. They are also given more freedom with their time. So, we predict a relationship between mental health and low amounts of sleep-in students. In contrast, the alternative outcome is that there will be no mental health problems arising as students lose sleep for long periods. Since getting good sleep allows us to function better throughout our days, we will likely see the impact bad quality and quantity of sleep will have on…The National Science Foundation (NSF) paid for “systemic initiatives” to help cities to reform their public education systems in ways that should help students to learn better. The initiative in Chicago focused on improving the teaching of mathematics in high schools. The average scores of students on a standard test of math skills were higher after two years of the programs in 51 out of 60 high schools in the city. Leaders of NSF said that this was evidence that the Chicago program was succeeding. Critics said that this doesn’t say anything about the effect of the systematic initiative. Who is correctPlease help me better understand how to properly solve. A randomized controlled experiment in Charlotte, North Carolina, studied three police responses to spousal abuse: advise and possibly separate the couple, issue a citation to the offender, and arrest the offender. The effectiveness of the three responses was determined by re-arrest rates. The photo shows the rates. Research wishes to test null hypothesis that that the proportions of subsequent arrests are the same regardless of the treatment assigned. Under the null hypothesis, determine the expected number of times no subsequent arrest would occur for the treatment “Advise/separate”?
- Researchers have conducted a study to investigate the mathematical competency of primary school students from three different countries: Australia, Canada and America. It was hypothesised that mathematical competency would be highest for Canadian students, followed by Australian students, then American students. It was also hypothesised that the child's sex would moderate this relationship. Here, mathematical competency is measured on a continuous scale, with higher scores representing higher levels of competency. Which of the following would be an appropriate statistical test to conduct, which addresses these hypotheses? Group of answer choices: Mixed ANOVA Within subjects ANOVA Factorial ANOVA Multiple Regression Single Factor ANOVAHelp me!!Exercise is known to produce positive psychological effects. Interestingly, not all exercise is equally effective. It turns out that exercising in a natural environment (e.g., jogging in the woods) produces better psychological outcomes than exercising in urban environments or in homes (Mackay & Neill, 2010). Suppose that a sports psychologist is interested in testing whether there is a difference between exercise in nature and exercise in the lab with respect to post-exercise anxiety levels. The researcher recruits n 5 7 participants who exercise in the lab and exercise on a nature trail. The data below represent the anxiety scores that were measured after each exercise session. Treat the data as if the scores are from an independent-measures study using two separate samples, each with n 5 7 participants. Compute the pooled variance, the estimated standard error for the mean difference, and the independent-measures t statistic. Using a 5 .05, is there a significant difference…
