A p-value of 0.3 indicates that there is a 30% chance that the observed results are due to chance. However, the size of the sample can also have a significant impact on p-values. A small sample size can lead to inaccurate p-values, which can make it difficult to draw reliable conclusions. Therefore, the coach should not recommend stopping the new training regime solely based on the current p-value given the small sample size.
