Fatin conducted an experiment to investigate the impact of compost derived from four distinct spent-mushroom substrates (splitgill, ganoderma, black jelly, and oyster mushrooms) on the growth of rice seedlings in terms of height and biomass against conventional compost (control). The height and biomass data of rice seedlings are provided in the tables below: Table 1. Height of seedlings (cm) grown in the spent-mushroom substrate compost Spent-mushroom substrate compost Ganoderma BlackJelly 18.8 9.1 19.5 10.0 21.0 8.6 16.0 8.3 Replication Replicate 1 Replicate 2 Replication Replicate 3 Replicate 4 Control 13.0 17.0 19.0 15.0 Replicate 1 Replicate 2 Replicate 3 Replicate 4 Table 2.

He hypothesizes that this variation in the origin of the substrates might yield diverse outcomes in the compost's effectiveness. Can you validate Jamalee's assumption based on the results obtained?
