Considering the situation described, the scientist's null and alternative hypothesis are described by:
Null hypothesis 
; Alternative hypothesis 
.
<h3>What are the hypothesis tested?</h3>
At the null hypothesis, it is tested if there is no difference, that is, the difference of the means represented by 
is of 0, hence:
At the alternative hypothesis, it is tested if there is a difference, hence:
