In a recent study, researchers found that Americans worked an average of 34.5 hours per week (2,070 minutes). You expect that nurses work significantly more time per week than the national average. You find in a sample of 61 nurses, the average hours worked per week was 2,574 minutes with a standard deviation of 790 minutes. Use the critical-value approach for a t-test (where a = .001) to determine if there is a significant difference in amount of time worked per week between the national average and nurses. 1. List your degrees of freedom 2. List your t test statistic 3. List your critical t value(s) 4. Is the difference between the national average and nurses statistically significant? ( Yes/No)
