So let's first think about the mean number of fruit for freshmen. So essentially we're just gonna take each of these data points, add them all together, and then divide by the number of data points that we have. So we have one data point at zero. So we have one data point at zero, so I'll write zero. And then we have two data points at one. So we could say plus two times one. And then we have two data points at two.
