A medical school admissions officer was interested in whether there is a difference in MCAT test scores (the standardized test used for medical school admission) between (1) biological sciences majors, (2) social science majors and (3) math majors. The admissions officer randomly sampled 50 students from each of these majors who applied to medical school in 2014 and recorded their MCAT score.Here are the three sample standard deviations for the MCAT scores for the three groups (biological sciences majors, social sciences majors, math majors):Column Std. HeadBiological Sciences 5.3115216Social Sciences 6.1661669Math 4.7821787Based on this information, do the data meet the condition of equal population standard deviations for the use of the ANOVA? Yes, because 6.17 − 4.78 < 2. Yes, because 6.17/4.78 < 2. No, because the standard deviations are not equal.

The admissions officer randomly sampled 50 students from each of these majors who applied to medical school in 2014 and recorded their MCAT score.The following hypotheses were tested:H0: μ1 = μ2 = μ3Ha: μ1, μ2, μ3, are not all equalThe analysis was run on the data and the following output was obtained:ANOVA TableSource DF SS MS F-Stat P-ValueTreatments 2 304.11487 152.05743 5.1196003 0.0071Error 147 4366.0523 29.701036 Total 149 4670.1672 Which of the following is an appropriate conclusion based on the output? Fail to reject H0 and conclude that the data provide strong evidence that the three mean MCAT scores (representing the three majors) are not all equal. Fail to reject H0 and conclude that the data do not provide sufficient evidence that there is a relationship between the student’s major and MCAT score. Reject H0 and conclude that the data provide strong evidence that there is a relationship between the student’s major and MCAT score. Reject H0 and conclude that the data provide strong evidence that MCAT scores are related to student majors in the following way: the mean MCAT score for math majors is higher than the mean MCAT score for biological sciences majors, which in turn is higher than that of social sciences majors.

Sue took a test in both biology and math last week. The biology test had a mean of 70 and a standard deviation of 7, whereas the math test had a mean of 75 and a standard deviation of 10. Sue scored a 76 on the biology test and a 76 on the math test. On which test did she do better in comparison to the rest of the class?Choose onethe math testthe biology testShe did the same on each test.cannot be determined

There are several inaccuracies in the following paragraph. Using the provided sources, identify these inaccuracies and note the corrections (eg. the MCAT exam is listed as an education exam but should say medical exam.)What Is the General Science Praxis? The General Science Praxis exam is one of the Praxis subject assessments, which is part of the Praxis suite of exams. The Praxis suite includes the Praxis Core Tests, Praxis Subject Assessments, and Praxis Content Knowledge for Teaching (PKT) tests. Many U.S. states utilize one or more of these Praxis exams as a required part of the certification process for aspiring nurses. Candidates must pass their required Praxis exams to earn licensure or certification in a given subject area and/or grade level. The General Science Praxis exam costs $50 to take.Sources: https://www.ets.org/pdfs/praxis/5436.pdf https://www.ets.org/pdfs/praxis/praxis-information-bulletin.pdf **

On a nationwide test taken by high school students, the mean score was 49 and the standard deviation was 12. The scores were normally distributed. Complete the following statements.(a) Approximately 95% of the students scored between and .(b) Approximately of the students scored between 13 and 85.
