Fill in the missing values from the frequency table. And let's see, we have this raining days, not raining days, and the total days that he kept data for. And then he tabulated on, say, the raining day, whether his mom was grouchy or not grouchy, and on a not raining day, whether his mom was grouchy or not grouchy. And there was a total of 35 days it rained, 330 days that it didn't rain. And then 73 times his mom was grouchy and 292 times his mom was not grouchy. So the first thing that we said, well, how do we figure this out? We have these four boxes here.
