Thank you so much and I will rate right aways after received the answer

All the question need to be solved detailed especially in question 6. For the test, it should be nice if you code in Rstudio.

3:35 all LTE D Done HW_11_Chi_Square_blank Homework 11 You may either type your responses in a general word-processing program and embed screen shots in the document with your code, or you may use a markdown file with code chunks. Regardless of your choice, please make cer- tain that your numbering for your responses aligns with the numbering in this assignment. Anemia and Intellectual Disabilities Lin, Lin, Lin, Hsu, Lob, Yen, Fang, Chien, Tang and Wu (2010) conducted a study to see if there were any relationships between intellectual disabilities and anemia (a blood condition) . In 2008, physical examinations of over 900 chil- dren and adolescents with intellectual disabilities were taken. Blood hemoglobin concentration (Hb) was recorded for each individual since this can help deter- mine if an individual has anemia. If an individual has abnormal (low) Hb levels, that would indicate that the individual has anemia. Data from the study are given in the table below. Hemoglobin Concentration Normal Abnormal (low) Totals Disability Level Mild + Moderate 482 51 533 Severe + Profound 345 58 403 Totals 827 109 936 1. What is an observatinal unit (case)? 2. Identify the variables of interest and their types. 3. Based on your answer to the above, what type of test is appropriate to answer the research question? 4. Using words, identify the null hypothesis for this study. Your answer should be in terms of anemia and disabilities. 5. Identify the alternative hypothesis for this study.

Check Whether the conditions are met for you to proceed with the test. Justify your answer with appropriate reasoning. 7. Regardless of your answer to the previous question, henceforth you may assume conditions are met for conducting the appropriate inference. Use the method of your choice to conduct an appropriate test at a 0.05 sig- nicance level. Include a simulation screen shot or code to support your answer. 8. Does the p-value provide against the null hypothesis? 9. Interpret the meaning of your p-value. In other words, it is the probability of what given what? Or, Assuming What7 the p-value is the probability of what? 10. Based on your p-value, Write a conclusion in terms of anemia and disabil- ities
