A fishpond owner wants to determine if three different fish feed types significantly differ in terms of their effect on the growth of fishes. The three fish feed were used in three different ponds with the same depth, area, and water quality, each containing milkfish fry whose ages and sizes are almost the same. After 6 months, samples are caught from all three ponds and fish weight recorded. The null hypothesis for this analysis is: * O H1 = H2 = 13 O p1 - H2 = p3 -0 Not all the fish populations have the same mean weight. O At least one of the fish populations has a different mean weight. O Other
