Answer
None of the options provided is a correct interpretation of a p-value of 0.03.
Explanation
## Step 1:First, we need to understand what a p-value is. In statistical hypothesis testing, a p-value is the probability of obtaining test results at least as extreme as the results actually observed, under the assumption that the null hypothesis is correct. ## Step 2:A p-value of 0.03 means that there is a 3% chance of obtaining the observed results (or more extreme) if the null hypothesis is true. This is not a measure of the validity of the experimental results, nor is it a measure of the chance that the results are due to some aberration in the sample. ## Step 3:Therefore, the correct interpretation of a p-value of 0.03 is not about the validity of the results or the chance of aberration in the sample. It's about the probability of obtaining such results (or more extreme) assuming the null hypothesis is true.
