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?
UCLA conducted a survey of more than 263,000 college freshmen from 385 colleges in fall 2005. The results of students' expected majors by gender were reported in The Chronicle of Higher Education (2/2/2006). Suppose a survey of 5,000 graduating females and 5,000 graduating males was done as a follow-up last year to determine what their actual majors were. The results for males are shown in the table below. The second column in the table does not add to 100% because of rounding.Conduct a goodness-of-fit test to determine if the actual college majors of graduating males fit the distribution of their expected majors.

Major League Baseball (MLB) consists of 30 The earned run average, ERA, is a statistic used to measure a pitcher's (the person who throws the ball to the person trying to hit the ball) effectiveness. The lower the ERA, the more effective the pitcher is. Statisticians are trying to show there is a correlation between the team’s ERA and the number of wins. The data on the spreadsheet is from all the teams in the 2021 regular season. Find the equation for the regression line for this data. Find the correlation coefficient and R2. State the Null and Alternate Hypothesis. State Decision Rule and Critical Value at the 5% significance level (think about whether this should be a one or two tailed test and which test statistic needs to be calculated). Compute the test statistic and p-value. What is your decision concerning Null? What does that mean? If the ERA were 4.5, what is the predicted number of wins (ŷ) using the regression line? ERA to wins in 2021 (n = 30)…
A research study was conducted about gender differences in 'sexting'. The researcher believed that the proportion of girls involved in 'sexting' is different from the proportion of boys involved. The data collected in the spring of among a random sample of middle and high school students in a large school district in is summarized next: out of 380 females 43 sent 'sexts' and out of 410 males 64 sent 'sexts'. Is the proportion of girls sending sexts different from the proportion of boys 'sexting'? Choose the appropriate procedure. Procedure: Assumptions: (select everything that applies) Population standard deviations are known Normal populations Sample sizes are both greater than 30 Population standard deviation are unknown but assumed equal Paired samples Population standard deviation are unknown Simple random samples The number of positive and negative responses are both greater than 10 for both samples Independent samples
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 team of researchers working on the development of vaccines conducted a study on two vaccines. Thirty individuals participated in the study and were randomly assigned to two groups and one group received vaccine 1 and the other group vaccine 2. The researchers then measured the amount of antibody in the individuals' blood after ingestion, entered R and calculated some fish sizes that can be seen here below. x̄1 = 494,54, s1 =52,39, x̄2 = 467,93, s2 = 45,20, d = 26,61, sd = 68,69. Blood levels of antibodies can be expected to follow normal distribution. Use α = 0,05. c) What conclusion do you draw from the hypothesis test in point b about the possible difference in the mean amount of antibody after oral administration of the vaccines? d) The researchers also created a 95% confidence interval for the difference between the averages. Will the confidence interval contain the value 0? Justify your answer without calculating the confidence interval.e) Let us now assume that there is in fact…

Ministry of Environment and Water conducted a research regarding changes of the sea surface temperature that can affect some species of animal, plants, and microbes in Malaysia. Three islands from 42 Islands that gazed as Marine Park in Malaysia are randomly selected as the sample for this study, which are Kapas Island, Kuraman Island and Rusukan Island. For each island, the temperature (in °C) was measured for 50 days. The Microsoft Excel output of descriptive statistics for the data are summarized in Table 1.
