Step 1
It is given that there are three samples involve in the ANOVA. Therefore,
a).
The ANOVA is a technique which is used to determine whether the population of more than two groups are significantly different or not.
Here, there are 3 sample groups available in the ANOVA, it means that the population means would be 3 as well.
Thus, for the given case, we are trying to determine whether these three population groups' means are significantly different or not.

Step 1
b).
As per the above,
Consider that μ1,μ2 and μ3, are the population means for these 3 samples.
Thus, the null and alternate hypotheses are:
H0:μ1=μ2=μ3,
H1:(At least one mean is different)
