QuestionCarbon monoxide: A recent study examined the effects of carbon monoxide exposure on a group of construction workers. The following table presents the numbers of workers who reported various symptoms, along with the shift (morning, evening, or night) that they worked. \begin{tabular}{cccc} \hline & Morning Shift & Evening Shift & Night Shift \\ \cline { 2 - 4 } Influenza & 17 & 10 & 18 \\ Headache & 32 & 27 & 6 \\ Weakness & 11 & 18 & 9 \\ Shortness of Breath & 4 & 7 & 10 \\ \hline \end{tabular} Send data to Excel
Test the hypothesis of independence. Can you conclude that symptoms and shift are not independent? Use the $\alpha=0.10$ level of significance and the $P$-value method with the TI-84 Plus calculator.
