See below.
Work Step by Step
The null hypothesis says that the all population means are equal to each other:
$H_0:\mu_1=\mu_2=\mu_3$
The alternative hypothesis says the opposite of the null hypothesis, which is that at least one of the means doesn't equal all the others.
The F-statistic is under "F", thus $F=11.4257$.
The P-value is is under "P-value", thus $P=0.00205$.
$P\lt 0.05$, thus we reject the null hypothesis.
Thus there is evidence to support the claim that not all population means are equal.
