Fоur different fertilizers аre eаch tested оn six cherry tоmаto plants. The number of cherry tomatoes produced by each plant is recorded and given in the table below. Assume that the requirements of normality are met. Fertilizer 1 Fertilizer 2 Fertilizer 3 Fertilizer 4 16 18 16 13 17 15 13 15 16 15 14 13 15 15 13 14 17 15 12 14 16 16 13 15 At a 0.05 level of significance test to determine if the mean number of cherry tomatoes produced by the plants is the same for each fertilizer. 1. The conditions for the ANOVA test are met because: a. The requirements for normality are met. b. The four samples can be considered independent. c. The population variance values can be considered equal because [vari]. 1. Determine the null and alternative hypotheses Ho: All means are equal H1: [alt] 2.
