Given that the cows have been arranged by weight, it's likely that the cows are sorted in order from lightest to heaviest or vice versa. Therefore, there isn't a need to further arrange the cows by weight since they are already in order based on weight. The farmer should focus on determining the mean weight of the cows. This can be achieved by calculating the total weight of all cows and then dividing it by the number of cows. 1. **Calculate the total weight of the cows**: Add up the weights of all the cows. 2. **Determine the number of cows**: Count how many cows there are. 3. **Compute the mean weight**: Divide the total weight by the number of cows. **Mean weight** = (Total weight of cows) / (Number of cows) His goal is to check the average weight of all cows then he can compare or evaluate his cows with other farmers' cows.
