Part 1: The Goodness-of-fit test The problems in this section are taken directly from the course textbook. 1. A factory manager needs to understand how many products are defective versus how many are produced. The number of expected defects is listed in Table A. A random sample was taken to determine the actual number of defects. This information is contained in Table B below. Table A Number produced 0-100 101-200 201-300 301-400 401-500 Number defective 5 6 7 8 10 Number produced 0-100 101-200 (c) What are the degrees of freedom? 201-300 301-400 Table B 401-500 Number Defective 5 7 8 9 11 (a) Write out the null and alternative hypothesis. Use correct notation. Clearly label the claim. (b) Can a goodness-of-fit test be used? If your answer is, "yes," conduct the goodness-of-fit test. If you answer is, "no," explain why this test does not apply.

I need help with question 7
I am to do a project for an inferential statistics class and I would like some basic guidance. I am to propose a research question. My proposed research question is "Does drinking stimulants such as coffee improve a student's grades?" My question is what do you think the best population for such a question would be if I am strictly doing research off of the internet? What do you think the variables would be? What method of sampling do you think would be best to incorporate?

Please no written by hand solution and no img In a certain town a survey organization took a simple random sample of 225 homes to find the average price of a home. The sample average turned out to be $390,000. It was known that before the average price was $395,000 with an SD of $60,000. The organization was concerned that the average price has change with time. Can you say if the difference is a real change or just a chance variation?
Textbook question for practise - A behavioural psychologist has developed a cognitive-behavioural therapy (CBT) technique modified from classic systematic desensitization to reduce her patients’ phobia of spiders. She decides to test the effectiveness of her new therapy approach by selecting ten patients at random to undergo the treatment for 3 months. The patients were asked to rate how much fear they feel/experience when in the presence of a spider/spiders using a scale from 0 (no fear at all) to 100 (extreme panic and fear). They were tested before and after the therapy. The ratings for each patient are as follows: For this question, be sure to do the following: ▪ State the statistical hypotheses (using the appropriate notation). ▪ Indicate whether the research hypothesis is non-directional or directional (and how you know). ▪ Set the decision rules, which will include: o State alpha - 0.05% o Compute the degrees of freedom o Providing the critical value for the test statistic…
