To find the mean, we need to sum up all the weights and divide by the total number of weights. Using the table, we can find that the sum of all the weights is 538.6. Dividing this by 160 (the total number of weights) gives us 3.38. Therefore, the mean weight is 3.38 kilograms. The correct answer is D.
