Using the information given below with the results from the lab practical, Acknowledge when a hypothesis may be incorrect. Null hypothesis and alternative hypothesis which is hypothesis is rejected and which is accepted and rejected and why. State your explanation in detail in one paragraph in simple English terms.

F value. 16.835
P value. 0.00023
F critical 3.47805
With a Honest Significant Difference (HSD) 0.04256
Hypothesis
Null Hypothesis (H0): There is no significant difference in the antibacterial effectiveness of the plant-derived skincare products (herbal extracts, gentel, and macadamia oil) compared to the negative control (water) and the positive control (Ceftriaxone) in inhibiting bacterial growth as measured by the zones of inhibition on agar plates.
Alternate Hypothesis (H1): At least one of the plant-derived skincare products (herbal extracts, gentel, or macadamia oil) demonstrates a significantly greater antibacterial effectiveness in inhibiting bacterial growth compared to the negative control (water) and shows comparable or superior effectiveness to the positive control (Ceftriaxone) as measured by the zones of inhibition on agar plates.

Based on the results of the lab practical, we can conclude that the null hypothesis (H0) is rejected, and the alternative hypothesis (H1) is accepted. The F value of 16.835 is much greater than the F critical value of 3.47805, indicating a significant difference among the groups being tested. Additionally, the P value of 0.00023 is far below the common threshold of 0.05, which further supports a strong statistical significance. This means the data provides enough evidence to suggest that at least one of the plant-derived skincare products is significantly more effective in inhibiting bacterial growth than the negative control (water), and potentially has antibacterial effectiveness similar to or greater than the positive control (Ceftriaxone). Thus, we acknowledge that our initial assumption that there is no difference (null hypothesis) is incorrect, and we accept that at least one of the plant products performs better than just water.
