***Note: the first 6 questions refer to this information.** You are the Director of Safety, Health, and Environment for the chemical manufacturing arm of a large agriculture company. As part of your annual review of the company's integrated management system, you are tasked with analyzing injury and ilness data for your company to determine if the year's objectives have been met and to create new performance goals for the future. You were responsible for 20,000 full-time workers employed at 30 different facilities across the U.S. The larger facilities produce pesticides, fertilizer, feed additives and other agriculture products. Several smaller facilities are focused on research and development. One of your obiect es for last year was to reduce the number of total recordable injuries and illnesses per facility by 10% or more from the previous year. The data in the Table 1 below represent the true recordable injury and illness data for your chemical manufacturing division Table 1: Injury and illness experiences of 30 chemical manufacturing facilities in last two years YearTotal number of Average number of Total Recordable Case Rate llnesses injuries and injuries/illnesses per facility (# of injuries or illnesses per 10,000 workers) Mean (SD) (12) 1.7 (11) prior year 400 12.0 ast yecar 150 10.8 1. Without conducting any hypothesis testing, do your data appear to support the idea that your objective was achieved? Why or why not?Explanation / Answer
The objective is to reduce the number of total recordable injuries and illnesses per facility by 10% or more from the previous year. Without conducting any hypothesis testing, I do not support the idea that the objective was achieved. Because of the average number of injuries and illnesses at the prior year 80 is more than the last year 71.7.
