Explanation / Answer

SOlution:-

14) The difference was so small that it could have happened by chance even if the remedies were equivalent.

The result being not significant also means that p value is greater than 0.05, hence we can not reject the null hypothesis. So we have to accept the null hypotehsis which states that there is no diffference.
