PLEASE DO PART D The education department has conducted a survey to review student’s language ability. A sample of 40 boys and 40 girls have been selected randomly selected for an aptitude test. The test result is that 28 boys pass the test, and 32 girls pass the test.(a) Give a point estimate of the population proportion of boys can pass the aptitude test.(b) Give a point estimate of the population proportion of girls can pass the aptitude test.(c) Use the combined data of 80 students, give a point estimate of the population proportion of students can pass the aptitude test.(d) Use the combined data of 80 students, construct a 95% confidence interval estimate of the population proportion of students can pass the aptitude test.

Week 11 Discussion Board – Ethics in Statistics As you start working on your SEA course project, it is important that you also start to think about the idea of ethics in statistics. The Belmont Report (1976) summarizes ethical principles and guidelines for the research: Respect for Persons, Beneficence, and Justice. After watching the ethics video in this week’s module, respond to the discussion board. Initial Post Week 11 Discussion Board – Ethics in Statistics As you start working on your SEA course project, it is important that you also start to think about the idea of ethics in statistics. The Belmont Report (1976) summarizes ethical principles and guidelines for the research: Respect for Persons, Beneficence, and Justice. After watching the ethics video in this week’s module, respond to the discussion board. Initial Post For your post, consider one of the ethical principles from the Belmont report. How did the video discuss this principle?…

PLEASE DO PART D AND  PART E A research team is working on a project to study the time (in seconds) for high school male runners to finish a 400-meter race. Jimmy, a junior researcher in the team, has randomly selected a sample of 25 male runners from a high school and the time (in seconds) for each of them to complete a 400-meter race was recorded. The sample mean running time was 53 seconds. It is assumed that the running time in a 400-meter race follows a normal distribution with a population standard deviation of 5.5 seconds.(a) Give a point estimate of the population mean running time for a 400-meter race.(b) Calculate the sampling error at 95% confidence level.(c) Construct a 95% confidence interval estimate of the population mean running time for a 400-meter race.(d) If instead of 25, 80 male runners are selected for the study, what is the sampling error at 95% confidence level? When the 95% confidence interval is constructed based on a sample with 80 male runners, would you…

Using the excel template show the full steps to get the correct solution. Question: Yearly automobile inspections are required for residents of the state of Pennsylvania. Suppose that 12% of all inspected cars in Pennsylvania have problems that need to be corrected. Unfortunately, Pennsylvania state inspections fail to detect these problems 20% of the time. On the other hand, assume that an inspection never detects a problem when there is no problem. Consider a car that is inspected and is found to be free of problems. What is the probability that there is indeed something wrong that the inspection has failed to uncover?
