That's what we do with it. You call each of those entries in Excel also a cell, each of the entries in a table. What we do is we figure out what the expected value would have been if you do assume the null hypothesis. Then we find the squared distance from that expected value, and we, I guess you could call it, normalize it by the expected value, take the sum of all of those differences. And if those differences, those squared differences, are really big, the probability of getting it would be really small, and maybe we'll reject the null hypothesis. So let's just figure out how we can get the expected number. So we're assuming the herbs do nothing.
