A university has 4 different instructors teaching calculus 1. There have been complaints from students that one of the 4 instructors fail too many students and complaints from professors that one instructor gives too many A’s. The table (photo attached below) gives the number of ABC’s each professor gives along with the number of DFW’s. 3 sections for each teacher were randomly selected over the past 5 years for these values. Part 1) Test to see if the percent of students receiving an AB or C is different for the different instructors Part 2) If it is not the same create confidence interval using difference in proportions to find which ones are different from the others. HINT: start with the largest difference in percents first and work your way in. Thank you for your help!!

Q2) Independent-Samples t-Test (Round calculated results to the hundredth (2nd place to the right of the decimal)) In a research project, researchers collected demographic and health data from a sample of elderly residents in the community. To examine any possible gender differences in their sample, they want to see if the females and the males differ significantly on the education level (number of years of formal schooling). The researchers are not predicting any direction in the possible gender differences so the hypotheses should be non-directional. They would like to run a two-tailed test with α = .10.

Can you help me with the code for this in R please? 2. 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
