One-way ANOVA is used to compare means of three or more groups. In this case, we are comparing the mean temperatures in three greenhouses. Two-way ANOVA is used when we want to compare the effects of two different factors on a response variable. Test of independence is used to test if two categorical variables are independent of each other. Goodness-of-fit is used to test if a set of observed data follows a particular distribution. None of these tests is appropriate for testing the claim in this scenario. Therefore, the best choice is one-way ANOVA.
