Researchers wanted to compare the proportion of females who are left-handed to the proportion of males who are left-handed. The researchers randomly selected 815 females and 575 males. They observed that 66 of the females and 60 of the males were left-handed. We will test the claim that the proportion of females who are left-handed is lower than the proportion of males who are left-handed. We will test this claim at the 5% significance level
