A study is being performed to see if there is a correlation between the concentration of chromium in the blood and a suspected disease. Blood samples from a group of volunteers with history of the disease are analyzed and compared with the results from the healthy control subjects. From the following results (Table 1), determine whether the differences between the two groups can be ascribed as chance or whether they are real at 95% confident level.
