- 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?

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?Suppose that a person has a 5% chance of contracting COVID-19 attending a concert without wearing a mask. What is his chance of contracting COVID-19 if he attends concerts 20 times without wearing mask? Round your answer to three decimal places (such as 0.123).
- Let's assume that the COVID-19 new case report data were collected from S.A Ministry of Health 30th of December 2019 was the first date that COVID-19 was confirmed in S.A. The time period of data was from the 20th of January to the 27th of January 2020 (for the last 7 days). The data included the total number of new cases, date of recorded, number of new total COVID-19 cases. In this study, a medical researcher used Pearson's cortelation analysis and the linear regression model to predict COVID-19 new cases based on the available data. (e.g., that Cases of infection rises linearly with number of people tested). The best-known types of regression analysis are the following: Date Day Sunday Monday Tuesday Wednesday Thursday Friday Saturday Sunday Test No. Case Counts 2020/01/20 2020/01/21 2020/01/22 2020/01/23 2020/01/24 2020/01/25 2020/01/26 2020/01/27 6. 33 41 17 1 18 3. 13 44 Calculate the coefficient of correlation using the Karl Pearson method.

Knowing that this group has been the target of falsebeliefs about their religion, a researcher is interested in whether people who have moreinteractions with Muslim people are less likely to believe negative statements about Islam. To dothis, they surveyed a large sample of participants across Western Europe and asked themquestions about how frequently they interact with Muslim people as well as how much theyagreed with negative statements about Islam. What statistical test should be used to determine ifthere if how frequently survey participants interact with Muslim people predicts how likely theyare to agree with a negative statement about Islam? Assume parametric assumptions are met. A. Is this a relationship test or a difference test? Explain your rationale. B.
- please send me solution.URGENTDue to the alarming cases of Covid-19, a researcher wanted to study the characteristics of the patients in NCR infected by the virus. Lilliefors, a researcher, considered the following variables: M: age bracket (0-19, 20-39, 40-59, 60 and above) N: last country visited in the past 3 months O: number of days quarantined after manifestation of symptoms P: current status of the patient (mild, moderate, severe) 6. To answer the objective of the study, Lilliefors used different data collection methods. First, she gathered information about the variables of interest by letting the patients answer a self-administered questionnaire. Second, to supplement the data she gathered, she collected the sociodemographic profile of the patients using the data from the Department of Health. The methods of data collection used by Lilliefors are ________.

The frequencies were found to be 218, 130, 106, 83, 65, 48, 48, 37, and 59, and those digits correspond to the leading digits of 1, 2, 3, 4, 5, 6, 7, 8, and 9, respectively. If the observed frequencies are substantially different from the frequencies expected with Benford's law shown below, the check amounts appear to result from fraud. Use a 0.025 significance level to test for goodness-of-fit with Benford's law. Does it appear that the checks are the result of fraud?
