Answer 1

The p value represents the probability of occurrence of a given event. Usually, the p value of less than 0.05 is considered significant at 95% confidence intervals.

A) Here, the p value is 0.3520. So, there is no statistical significant difference in bacterial biodiversity.

B) The results support the null hypothesis.

C) The graph alone cannot be used to determine the presence of statistical significance because there is overlapping of error bars or 95% confidence intervals between individual bars.
