A company is interested in the satisfaction of their employees,so they hired a consulting firm to conduct an in-house study.Employees were classified into three categories (support staff,analysts and executives) and asked if they felt the company had ahealthy work environment.
The data:
| Yes | No |
| Support staff | 9 | 32 |
| Analysts | 14 | 37 |
| Executives | 12 | 5 |
You're interested in whether employee classification hasanything to do with attitudes about work environment. For step 1,instead of re-writing this question of interest, instead saywhether the appropriate comparison is across columns, or acrossrows.
Step 2: State the null hypothesis.
Step 3: State the alternative hypothesis.
Step 4: What is the correct level of alpha, and which tailsmatter? Choose all statments that are correct.
Step 5: Which statistical test are you using?
Step 6: What is the value of the test statistic?
Step 6 continued: How many degrees of freedom in this test?
Step 7: What is the critical value for the test statistic?
Step 8: How does the test statistic compare to the criticalvalue?
Step 9: Based on this comparison, do you accept or reject yournull hypothesis?
Step 10: What do you conclude from this analysis?
