Question

if our p-value is less than 0.05, then we reject the null hypothesis we reject the alternative hypothesis we reject the biological hypothesis the biological hypothesis is proven

Explanation:

In hypothesis testing, the p - value is compared to a significance level (commonly 0.05). If the p - value is less than 0.05, we reject the null hypothesis. Rejecting the alternative hypothesis is incorrect (we either reject the null or fail to reject it, and we don't directly reject the alternative). "Biological hypothesis" is not a standard term in general hypothesis testing, and we never "prove" a hypothesis (we support or reject based on evidence), so the correct option is the one about rejecting the null hypothesis.

Answer:

We reject the null hypothesis
