Beryllium disease: Beryllium is an extremely lightweight metal that is used in many industries, such as aerospace and electronics. Long-term exposure to beryllium can cause people to become sensitized. Once an individual is sensitized, continued exposure can result in chronic beryllium disease, which involves scarring of the lungs. In a study of the effects of exposure to beryllium, workers were categorized by their duration of exposure (in years) and by their disease status (diseased, sensitized, o normal). The results were as follows: Duration of Exposure <1 1 to <5 > 5 Diseased 15 19 Sensitized 12 22 14 Normal 66 145 197 Send data to Excel Test the hypothesis of independence. Use the a = 0.10 level of significance and the P-value method with the TI-84 Plus calculator What do you conclude?
