A clinical psychologist claims that social support causes life satisfaction to increase.They want to test this experimentally by having 6 students receiving additional social support intheir fall semester and then assessing life satisfaction of participants (u1 = mu1). Then the same 6students receive no additional social support in their spring semester and are assessed on their lifesatisfaction during finals (u2 = mu2) and they want to assess if the difference in stress with noadditional finals relative to additional finals with mu1 - mu2.H1 = mu1 = Additional social support andH2 = mu2 = No additional social supportThey get the following data:Additional social supportNo Additional social support716969609294777437559963What would be the standard deviation of the difference scores? Please compute and report to 4decimal places.

Your research group wants to explore the possibility that a particular kind of Tibetan meditation (shamata meditation) increases the capacity of iconic memory. You go to a center where experienced Tibetan Buddhist meditators regularly practice. You randomly select 10 of these people to participate in your experiment. Your dependent variable is the number of digits recalled from iconic memory. You test them before and after a 5 weeks' intensive meditation course. You predict that their iconic memory will be enhanced (better recall) as a result of the attentional training that the meditation gives. Here is the data you collect: Before: 6;6;6;7;5;7;5;5;6;6 After: 8;7;7;8;7;8;6;7;6;8 1. What is the null hypothesis? What is the alternative hypothesis? (use symbols and not words)
A clinical trial is conducted to compare an experimental medication to placebo to reduce the symptoms of asthma. Two hundred participants are enrolled in the study and randomized to receive either the experimental medication or placebo. The primary outcome is self-reported reduction of symptoms. Among 100 participants who receive the experimental medication, 38 report a reduction of symptoms as compared to 21 participants of 100 assigned to placebo. When you test if there is a significant difference in the proportions of participants reporting a reduction of symptoms between the experimental and placebo groups. Use α = 0.05. What should the researcher’s conclusion be for a 5% significance level? Reject H0because 2.64 ≥ 1.960. We have statistically significant evidence at α = 0.05 to show that there is a difference in the proportions of patients reporting a reduction in symptoms. We reject H0 at the 5% level because 2.64 is greater than 1.96. We do have statistically…
Imagine you are a statistical consultant and your client, a weightlifting supplement company, is looking to see if their product is effective in increasing muscle mass gained over a training cycle. You randomly sampled 20 female weightlifters and assigned them to take the supplement and 20 to take a placebo. You have both groups run the same controlled training program over 12 weeks and calculated their whole body lean mass difference in pounds from the beginning to the end of the program. Can you infer that the supplement group gained more muscle mass on average than the placebo group? Use a = 0.05 for any hypothesis test. પ્રમ 1) State the research question in one sentence and use the question to determine the parameter we are using to conduct statistical inference. Describe this parameter in one sentence using symbols and a description. manu Aren
It is well demonstrated that the Parent-Child Interaction Therapy (PCIT) has a statistically significant effect on reducing children's disruptive behaviors for children with disruptive behavior disorders (DBD). A research team is interested in the gender differences of the PCIT effect and wondered does boys benefit more than girls in PCIT. To answer the question, the research team recruited 12 children with DBD who have enrolled in the PCIT for 3 weeks and asked their parents how much progress they have made during the therapy. Among these 12 children with DBD, 6 of them are girls, and 6 of them are boys. a) What is the research question? b) What is/are the variable(s)? What graphs can be used to display the variable(s) visually? c) What statistical test can be used to answer the research question?
A study is being planned to compare the effects of 2 different exercise protocols on the fine motor control of children with developmental delays. The children from a preschool for special needs childřen are targeted as subjects for this study. There are two classrooms specifically for these children, so each classroom is assigned to one of the 2 protocols. Classroom X gets the usual exercise protocol, while Classroom Y receives the newly designed exercise protocol. A test that includes letter tracing as a measure of fine motor control is administered to the children before and after the 16 weeks of the exercise protocols. What is the most Ilkely threat to internal validity? regression to the mean O selection error O mortality maturation
Average IQ scores for young school children are known to be 100 (SD = 15). However, the literature indicates that children’s intelligence may be decreased if their mothers have German measles during pregnancy. Using hospital records, a researcher obtained a sample of n = 25 school children whose mothers all had German measles during their pregnancies. Do the data indicate that children born to mothers who had German measles during the pregnancy have significantly lower IQ scores than typical young school children? DATA (Fictional) child IQ scr 1 91 2 111 3 97 4 95 5 96 6 95 7 95 8 96 9 94 10 93 11 95 12 92 13 96 14 91 15 97 16 93 17 92 18 99 19 93 20 97 21 85 22 94 23 96 24 95 25 96 Looking at the research scenario for this lab, you will see that it says, “ literature indicates that children’s intelligence may…
A team of social workers wants to compare the different effects of treatments for complex trauma. They divide 21 clients into 3 groups (n=7 each) that donot differ significantly from one another in terms of pretreatment trauma. one group gets (TFCBT), one group gets (EGT) and one receives a combination of the two (TF+EG). Clients symptoms are evaluated after treatment using a clinician interview where scores from range from 0-30 and higher scores indicate a higher severity. What test should be ran to see if there is a difference in post-treatment scores among the three treatments, and what graph should I use?

Alzheimer’s Testing for Alzheimer’s disease can be along and expensive process, consisting of lengthy testsand medical diagnosis. Recently, a group of researchers(Solomon et al., 1998) devised a 7-minute test to serveas a quick screen for the disease for use in the general population of senior citizens. A patient who tested posi-tive would then go through the more expensive battery of tests and medical diagnosis. The authors reported a falsepositive rate of 4% and a false negative rate of 8%.a) Put this in the context of a hypothesis test. What arethe null and alternative hypotheses?b) What would a Type I error mean?c) What would a Type II error mean?d) Which is worse here, a Type I or Type II error? Explain.e) What is the power of this test?
