In a study of 465 women, researchers wanted to evaluate if education level was related to the stage of cancer at the initial diagnosis by a doctor. Results of the data are presented on the right: What type of data is the stage of cancer? Quantitative, continuous Categorical, nominal Education 6 years 7-12 years Some college College grad.

Question
C. Don't use the test you mentioned in part b. Instead, we'll use one of the tests to determine if the amount of people's education is related to the stage of cancer that people have when they are initially diagnosed by a doctor. i. Which test are you using? ii. Determine the expected value for 7-12 year olds with Stage Il cancer and college graduates with Stage III cancer (these two cells only). Determine the test score for these same two cells (only). iii. iv. State the null and alternative hypotheses. v. The total test score value for this problem is 20.8. State the critical value, degrees of freedom, if you accept or reject the null hypothesis, and state your conclusion.
