To find the mean of a distribution, we add up all the values and divide by the total number of values. Using the provided frequency distribution, we can calculate the mean as follows:

(2 x 20) + (4 x 40) + (8 x 60) + (5 x 80) + (1 x 100) = 200 + 160 + 480 + 400 + 100 = 1,240
Total number of values: 20

Mean = 1,240/20 = 62

Therefore, the mean daily production is 106.4 (option D).
