From the following four observations among the given hypothesis with significance level is 0.05 the null hypothesis is not true.
Null hypothesis is all means are equal and in alternative at least there is a difference in one mean.
As given in the question,
Significant level is equal to 0.05
a. Null hypothesis : Null hypothesis is the one where there is no significant difference between the means of all the treatment groups.
Where as alternative hypothesis is the one which represents that there is significant difference between the means of all the treatment groups.
Therefore, from the following four observations among the given hypothesis with significance level is 0.05 the null hypothesis is not true.
Null hypothesis is all means are equal and in alternative at least there is a difference in one mean.
