And we're wondering, do they have the same preferences for subject domains? Are they equally inclined to science, technology, engineering, math, humanities, or neither? And so we can set up our null and alternative hypotheses. Our null hypothesis is that there is no difference in the distribution between left-handed and right-handed people in terms of their preference for subject domains. So no difference in subject, subject preference for left and right, for left and right-handed folks. And then the alternative hypothesis, well, no, there is a difference. So there is a difference.
