Question

1. if the p - value is greater than 0.05, what should you do?

option 1: prove the null hypothesis is true
option 2: accept the alternative hypothesis as true without doubt
option 3: reject the null hypothesis
option 4: fail to reject the null hypothesis

Explanation:

In hypothesis testing, a p-value greater than the significance level (0.05 here) means there is insufficient evidence to reject the null hypothesis. We do not "prove" the null hypothesis is true—we only fail to reject it when the evidence is weak.

Answer:

Fail to reject the null hypothesis
