Question
In a random sample of men from Cornwall, 22 were left-handed and 218 were right-handed. In a random sample of women from Cornwall, 64 were left-handed and 456 were right-handed. Use a 0.01 significance level to test the claim that the proportion of left-handed Cornish men is lower than the proportion of left-handed Cornish women. You may use the Ztable.pdf or the critical values below.

Critical Values:

\[
\begin{array}{|c|c|c|c|c|c|}
\hline
z_{0.005} = 2.575 & z_{0.01} = 2.325 & z_{0.025} = 1.96 & z_{0.05} = 1.645 & z_{0.10} = 1.282 \\
\hline
\end{array}
