Is there a relationship between gender and relative finger length? To investigate, a random sample of 452 U.S. high school students was selected. The two-way table shows the gender of each student and which finger was longer on his or her left hand (index finger or ring finger). State the hypotheses for a test of the relationship between gender and relative finger length for U.S. high school students.
$$\begin{array}{|l|c|r|c|} \hline & \text { Female } & \text { Male } & \text { Total } \\ \hline \text { Index finger } & 78 & 45 & 123 \\ \hline \text { Ring finger } & 82 & 152 & 234 \\ \hline \text { Same length } & 52 & 43 & 95 \\ \hline \text { Total } & 212 & 240 & 452 \\ \hline \end{array}$$
