In this study, we tested the antibacterial effectiveness of various plant-derived skincare products against bacterial growth, with the null hypothesis (H0) positing no significant difference in effectiveness compared to the controls, while the alternative hypothesis (H1) suggested that at least one product would exhibit superior antibacterial activity. The obtained F value of 16.835 significantly exceeds the F critical value of 3.47805, indicating a clear rejection of the null hypothesis. Additionally, the P value of 0.00023 further supports this rejection as it is much lower than the typically accepted alpha level of 0.05, suggesting that the observed differences are statistically significant. The Honest Significant Difference (HSD) of 0.04256 implies that the antibacterial effectiveness of at least one of the tested plant-derived products is indeed greater than that of the negative control and, importantly, may approach or surpass that of the positive control. This finding aligns with previous studies that have highlighted the potential of plant-derived compounds as effective antibacterial agents, thus reinforcing the idea that these natural extracts may serve as viable alternatives to conventional antibiotics, particularly in skin care formulations. Through rigorous statistical analysis, this study provides robust evidence against the null hypothesis, reinforcing the efficacy of the plant-derived skincare products in inhibiting bacterial growth.

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.
