A hypothesis test is appropriate to compare means of a continuous variable in two or more independent comparison groups.
The null hypothesis in ANOVA is always that there is no difference in means. The research or alternative hypothesis is always that the means are not all equal The result of hypothesis captures any difference in means and test the significance
