Please answer the questions carefully to get the right answers when you read the passage on Brain Hippocampal. Brain Hippocampal SizeA recent study¹ examined the relationship between football playing and hippocampal volume, in µL, in the brain. We use the n = 25participants in the control group to estimate average brain hippocampus volume for all non-football playing people.

П. STA requires each student to train a rat to perform specific behaviors. Student grades are determined by the rats' performance. Mr. Simmons is concerned that students who have prior experience with training rats or other animals may have an advantage. To test the hypothesis, she gave each student a survey at the start of the class. The survey asked students about their previous animal related experiences. At the course's conclusion, she compared the rats' learning for students with prior animal experience to students without. Do the data suggest a significant difference between the two groups of students? Rat scores for students with animal Rat scores for students with no experience experience n = 15 М-66 n = 10 M= 78 SS = 1420 SS = 2030 State the hypotheses, critical values with df and alpha = .05, calculate the test statistic and show all your work for each step of the calculations, answer the question stated above in bold-italics, AND state your conclusion using the 3-sentence…

The article ["CSI Effect Has Juries Wanting More Evidence" (USA Today, 2004)](https://usatoday30.usatoday.com/news/nation/2004-08-05-csi-effect_x.htm) examines how the popularity of crime-scene investigation television shows in influencing jurors' expectation of what evidence should be produced at a trial. In a survey of 500 potential jurors, one study found that 350 were regular watchers of at least one crime-scene forensics television series. i) Assuming that it is reasonable to regard this sample of 500 potential jurors as representative of potential jurors in the US, use the given information to construct and interpret a 95\% confidence interval for the proportion of all potential jurors who regularly watch at least one crime-scene investigation series. ii) Using the same sample proportion as part (i), construct a 95\% confidence interval for same proportion but instead use a sample size of 50. iii)…
Alzheimer’s disease is a progressive, irreversible disorder, and at this time the cause and cureare unknown. However, researchers at the University of Minnesota developed a brief, efficientand accurate means of predicting Alzheimer’s is persons from 65 to 85 years of age. The testtakes about 10 minutes and requires the patient to try to recall 10 words after using each wordtwice in sentences. According to the researchers, the test results are accurate 95% of the time.If the test is administered to a random sample of 25 persons from 65 to 85 years of age, what isthe probability that the test results are inaccurate for more than 12% of those persons sampled.Show your work and give your answer in the form of a sentence
