Below are a subset of data from a workplace safety survey. Using a .01 level of significance, determine whether these samples of women and men have significantly different levels of safety knowledge. Use these samples to answer questions 16-20. Men Women 4 7 6 5 7 6 3 7 NOTE: #16-20 assume you are doing an independent-samples t-test to answer this question. However, if you prefer to use an ANOVA, you are allowed to do so. Simply leave the answers to 16-20 blank (you'll temporarily get a 0 for them), and instead answer each question using an ANOVA when showing your written work to perform the 5 hypothesis testing steps with an ANOVA. After your uploaded work is graded, we can substitute the correct number of points you earned for these questions. Which of the following correctly represents the null and alternative hypothesis (MUST SHOW WORK FOR THIS PROBLEM)? Group of answer choices: a. H0: μmen< μwomen, H1: μmen≥ μwomen b. H0: μmen> μwomen, H1: μmen≤ μwomen c. H0: μmen- μwomen ≠ 0, H1: μmen- μwomen = 0 d. H0: μmen- μwomen = 0, H1: μmen- μwomen ≠ 0 Which of the following represents the proper critical region (MUST SHOW WORK FOR THIS PROBLEM). Group of answer choices a. tcrit=± 3.35 b. tcrit=± 3.71 c. tcrit=± 3.50 d. tcrit=± 1.96 Compute the test statistic (t-obs) (MUST SHOW WORK FOR THIS PROBLEM).
