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, or normal). The results were as follows:     Duration of Exposure   <1 1  to  <5 ≥5 Diseased 12 14 23 Sensitized 12 18 12 Normal 64 130 205   Test the hypothesis of independence. Use the =α0.01 level of significance and the P-value method with the TI-84 Plus calculator. What do you conclude?   Find P value

Question

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, or normal). The results were as follows:

 

  Duration of Exposure
 
<1
1
 to 
<5
≥5
Diseased
12
14
23
Sensitized
12
18
12
Normal
64
130
205
 

Test the hypothesis of independence. Use the =α0.01 level of significance and the P-value method with the TI-84 Plus calculator. What do you conclude?
