Example 151: In the following study, three kinds of fertilizer were compared. The researchers applied each fertilizer to five orchids. Each of the fifteen orchids was randomly assigned to one of the three fertilizers. At the end of the one year, the heights (in ft) of the plants were recorded. Test the claim at the 1% significance level that at least one of the three fertilizers has a different effect on orchid height.
