Question 19 2 pts In occupational and environmental toxicology research, researchers sometimes test how long it takes subjects to complete different physical tests (reaction times, times to complete delicate puzzles, etc) in order to assess nerve and motor damage attributed to pesticide exposure. In one study, a sample of 49 migrant workers (who have all had high levels of pesticide exposure) had a mean completion time of 59.4 seconds on a pegboard test. The state norms for this test have a mean of 50 and a standard deviation of 4.2. A researcher wants to know if the migrant workers had a harder time completing this test than the average person (alpha=.05). 15.67, p.05 Two-tail test
